|
| 16933 | * Create a Matrix. The function creates a new `math.Matrix` object from
|
| 16934 | * an `Array`. A Matrix has utility functions to manipulate the data in the
|
| 16935 | * matrix, like getting the size and getting or setting values in the matrix.
|
| 16936 | * Supported storage formats are 'dense' and 'sparse'.
|
| 16937 | *
|
| 16938 | * Syntax:
|
| 16939 | *
|
| 16940 | * math.matrix() // creates an empty matrix using default storage format (dense).
|
| 16941 | * math.matrix(data) // creates a matrix with initial data using default storage format (dense).
|
| 16942 | * math.matrix('dense') // creates an empty matrix using the given storage format.
|
| 16943 | * math.matrix(data, 'dense') // creates a matrix with initial data using the given storage format.
|
| 16944 | * math.matrix(data, 'sparse') // creates a sparse matrix with initial data.
|
| 16945 | * math.matrix(data, 'sparse', 'number') // creates a sparse matrix with initial data, number data type.
|
| 16946 | *
|
| 16947 | * Examples:
|
| 16948 | *
|
| 16949 | * let m = math.matrix([[1, 2], [3, 4]])
|
| 16950 | * m.size() // Array [2, 2]
|
| 16951 | * m.resize([3, 2], 5)

|
| 26618 | * Where:
|
| 26619 | *
|
| 26620 | * - `value: *`
|
| 26621 | * The value to be formatted
|
| 26622 | * - `options: Object`
|
| 26623 | * An object with formatting options. Available options:
|
| 26624 | * - `notation: string`
|
| 26625 | * Number notation. Choose from:
|
| 26626 | * - 'fixed'
|
| 26627 | * Always use regular number notation.
|
| 26628 | * For example '123.40' and '14000000'
|
| 26629 | * - 'exponential'
|
| 26630 | * Always use exponential notation.
|
| 26631 | * For example '1.234e+2' and '1.4e+7'
|
| 26632 | * - 'engineering'
|
| 26633 | * Always use engineering notation.
|
| 26634 | * For example '123.4e+0' and '14.0e+6'
|
| 26635 | * - 'auto' (default)
|
| 26636 | * Regular number notation for numbers having an absolute value between
|
| 26637 | * `lower` and `upper` bounds, and uses exponential notation elsewhere.
|
| 26638 | * Lower bound is included, upper bound is excluded.
|
| 26639 | * For example '123.4' and '1.4e7'.
|
| 26640 | * - `precision: number`
|
| 26641 | * A number between 0 and 16 to round the digits of the number. In case
|
| 26642 | * of notations 'exponential', 'engineering', and 'auto', `precision`
|
| 26643 | * defines the total number of significant digits returned.
|
| 26644 | * In case of notation 'fixed', `precision` defines the number of
|
| 26645 | * significant digits after the decimal point.
|
| 26646 | * `precision` is undefined by default.
|
| 26647 | * - `lowerExp: number`
|
| 26648 | * Exponent determining the lower boundary for formatting a value with
|
| 26649 | * an exponent when `notation='auto`. Default value is `-3`.
|
| 26650 | * - `upperExp: number`
|
| 26651 | * Exponent determining the upper boundary for formatting a value with
|
| 26652 | * an exponent when `notation='auto`. Default value is `5`.
|
| 26653 | * - `fraction: string`. Available values: 'ratio' (default) or 'decimal'.
|
| 26654 | * For example `format(fraction(1, 3))` will output '1/3' when 'ratio' is
|
| 26655 | * configured, and will output `0.(3)` when 'decimal' is configured.
|
| 26656 | * - `callback: function`
|
| 26657 | * A custom formatting function, invoked for all numeric elements in `value`,
|
| 26658 | * for example all elements of a matrix, or the real and imaginary
|
| 26659 | * parts of a complex number. This callback can be used to override the
|
| 26660 | * built-in numeric notation with any type of formatting. Function `callback`
|
| 26661 | * is called with `value` as parameter and must return a string.
|
| 26662 | *
|
| 26663 | * When `value` is an Object:
|
| 26664 | *
|
| 26665 | * - When the object contains a property `format` being a function, this function
|
| 26666 | * is invoked as `value.format(options)` and the result is returned.
|
| 26667 | * - When the object has its own `toString` method, this method is invoked
|
| 26668 | * and the result is returned.
|
| 26669 | * - In other cases the function will loop over all object properties and
|
| 26670 | * return JSON object notation like '{"a": 2, "b": 3}'.
|
| 26671 | *
|
| 26672 | * When value is a function:
|
| 26673 | *
|
| 26674 | * - When the function has a property `syntax`, it returns this
|
| 26675 | * syntax description.
|
| 26676 | * - In other cases, a string `'function'` is returned.
|
| 26677 | *
|
| 26678 | * Examples:
|
| 26679 | *
|
| 26680 | * math.format(6.4) // returns '6.4'
|
| 26681 | * math.format(1240000) // returns '1.24e6'
|
| 26682 | * math.format(1/3) // returns '0.3333333333333333'
|
| 26683 | * math.format(1/3, 3) // returns '0.333'
|
| 26684 | * math.format(21385, 2) // returns '21000'
|
| 26685 | * math.format(12e8, {notation: 'fixed'}) // returns '1200000000'
|
| 26686 | * math.format(2.3, {notation: 'fixed', precision: 4}) // returns '2.3000'
|
| 26687 | * math.format(52.8, {notation: 'exponential'}) // returns '5.28e+1'
|
| 26688 | * math.format(12400,{notation: 'engineering'}) // returns '12.400e+3'
|
| 26689 | * math.format(2000, {lowerExp: -2, upperExp: 2}) // returns '2e+3'
|
| 26690 | *
|
| 26691 | * function formatCurrency(value) {
|
| 26692 | * // return currency notation with two digits:
|
| 26693 | * return '$' + value.toFixed(2)
|

|
| 29431 | *
|
| 29432 | * For numeric values, the function works the same as `math.compare`.
|
| 29433 | * For types of values that can't be compared mathematically,
|
| 29434 | * the function compares in a natural way.
|
| 29435 | *
|
| 29436 | * For numeric values, x and y are considered equal when the relative
|
| 29437 | * difference between x and y is smaller than the configured epsilon.
|
| 29438 | * The function cannot be used to compare values smaller than
|
| 29439 | * approximately 2.22e-16.
|
| 29440 | *
|
| 29441 | * For Complex numbers, first the real parts are compared. If equal,
|
| 29442 | * the imaginary parts are compared.
|
| 29443 | *
|
| 29444 | * Strings are compared with a natural sorting algorithm, which
|
| 29445 | * orders strings in a "logic" way following some heuristics.
|
| 29446 | * This differs from the function `compare`, which converts the string
|
| 29447 | * into a numeric value and compares that. The function `compareText`
|
| 29448 | * on the other hand compares text lexically.
|
| 29449 | *
|
| 29450 | * Arrays and Matrices are compared value by value until there is an
|
| 29451 | * unequal pair of values encountered. Objects are compared by sorted
|
| 29452 | * keys until the keys or their values are unequal.

|
| 32520 | * const a = new Unit(5, 'cm') // 50 mm
|
| 32521 | * const b = Unit.parse('23 kg') // 23 kg
|

|
| 32525 | * @class Unit
|
| 32526 | * @constructor Unit
|
| 32527 | * @param {number | BigNumber | Fraction | Complex | boolean} [value] A value like 5.2
|

|
| 57209 | * Simplify an expression tree.
|
| 57210 | *
|
| 57211 | * A list of rules are applied to an expression, repeating over the list until
|
| 57212 | * no further changes are made.
|
| 57213 | * It's possible to pass a custom set of rules to the function as second
|
| 57214 | * argument. A rule can be specified as an object, string, or function:
|
| 57215 | *
|
| 57216 | * const rules = [
|
| 57217 | * { l: 'n1*n3 + n2*n3', r: '(n1+n2)*n3' },
|
| 57218 | * 'n1*n3 + n2*n3 -> (n1+n2)*n3',
|
| 57219 | * function (node) {
|
| 57220 | * // ... return a new node or return the node unchanged
|
| 57221 | * return node
|
| 57222 | * }
|
| 57223 | * ]
|
| 57224 | *
|
| 57225 | * String and object rules consist of a left and right pattern. The left is
|
| 57226 | * used to match against the expression and the right determines what matches
|
| 57227 | * are replaced with. The main difference between a pattern and a normal
|
| 57228 | * expression is that variables starting with the following characters are
|
| 57229 | * interpreted as wildcards:
|
| 57230 | *
|
| 57231 | * - 'n' - matches any Node
|
| 57232 | * - 'c' - matches any ConstantNode
|
| 57233 | * - 'v' - matches any Node that is not a ConstantNode
|
| 57234 | *
|
| 57235 | * The default list of rules is exposed on the function as `simplify.rules`
|
| 57236 | * and can be used as a basis to built a set of custom rules.
|
| 57237 | *
|
| 57238 | * For more details on the theory, see:

|
| 57242 | *
|
| 57243 | * An optional `options` argument can be passed as last argument of `simplify`.
|
| 57244 | * There is currently one option available: `exactFractions`, a boolean which
|
| 57245 | * is `true` by default.
|
| 57246 | *
|
| 57247 | * Syntax:
|
| 57248 | *
|
| 57249 | * simplify(expr)
|
| 57250 | * simplify(expr, rules)
|
| 57251 | * simplify(expr, rules)
|
| 57252 | * simplify(expr, rules, scope)
|
| 57253 | * simplify(expr, rules, scope, options)
|
| 57254 | * simplify(expr, scope)
|
| 57255 | * simplify(expr, scope, options)
|
| 57256 | *
|
| 57257 | * Examples:
|
| 57258 | *
|
| 57259 | * math.simplify('2 * 1 * x ^ (2 - 1)') // Node "2 * x"
|
| 57260 | * math.simplify('2 * 3 * x', {x: 4}) // Node "24"
|
| 57261 | * const f = math.parse('2 * 1 * x ^ (2 - 1)')
|
| 57262 | * math.simplify(f) // Node "2 * x"
|
| 57263 | * math.simplify('0.4 * x', {}, {exactFractions: true}) // Node "x * 2 / 5"
|
| 57264 | * math.simplify('0.4 * x', {}, {exactFractions: false}) // Node "0.4 * x"
|
| 57265 | *
|
| 57266 | * See also:
|
| 57267 | *
|
| 57268 | * derivative, parse, evaluate, rationalize
|
| 57269 | *
|
| 57270 | * @param {Node | string} expr
|
| 57271 | * The expression to be simplified
|
| 57272 | * @param {Array<{l:string, r: string} | string | function>} [rules]
|
| 57273 | * Optional list with custom rules
|
| 57274 | * @return {Node} Returns the simplified form of `expr`

|
| 57964 | * The derivative will be taken over the supplied variable in the

|
| 57982 | * math.derivative('2*x', 'x').evaluate() // number 2
|

|
| 61282 | *
|
| 61283 | * This function is only available on a mathjs instance created using `create`.
|
| 61284 | *
|
| 61285 | * Syntax:
|
| 61286 | *
|
| 61287 | * math.import(functions)
|
| 61288 | * math.import(functions, options)
|
| 61289 | *
|
| 61290 | * Where:
|
| 61291 | *
|
| 61292 | * - `functions: Object`
|
| 61293 | * An object with functions or factories to be imported.
|
| 61294 | * - `options: Object` An object with import options. Available options:
|
| 61295 | * - `override: boolean`
|
| 61296 | * If true, existing functions will be overwritten. False by default.
|
| 61297 | * - `silent: boolean`
|
| 61298 | * If true, the function will not throw errors on duplicates or invalid
|
| 61299 | * types. False by default.
|
| 61300 | * - `wrap: boolean`
|
| 61301 | * If true, the functions will be wrapped in a wrapper function
|
| 61302 | * which converts data types like Matrix to primitive data types like Array.
|
| 61303 | * The wrapper is needed when extending math.js with libraries which do not
|
| 61304 | * support these data type. False by default.
|
| 61305 | *
|
| 61306 | * Examples:
|
| 61307 | *
|
| 61308 | * import { create, all } from 'mathjs'
|
| 61309 | * import * as numbers from 'numbers'
|

|
| 61312 | * const math = create(all)

|
| 61315 | * math.import({
|
| 61316 | * myvalue: 42,
|
| 61317 | * hello: function (name) {
|
| 61318 | * return 'hello, ' + name + '!'
|
| 61319 | * }
|
| 61320 | * })
|
| 61321 | *
|
| 61322 | * // use the imported function and variable
|
| 61323 | * math.myvalue * 2 // 84
|
| 61324 | * math.hello('user') // 'hello, user!'
|
| 61325 | *

|
| 61329 | *
|
| 61330 | * math.fibonacci(7) // returns 13
|

|
| 61920 | * The object can contain nested objects,
|
| 61921 | * all nested objects will be flattened.
|
| 61922 | * @param {Object} [config] Available options:
|
| 61923 | * {number} epsilon
|
| 61924 | * Minimum relative difference between two
|
| 61925 | * compared values, used by all comparison functions.
|

|
| 61930 | * {number} precision
|
| 61931 | * The number of significant digits for BigNumbers.
|
| 61932 | * Not applicable for Numbers.
|

|
| 61935 | * output type depends only on the input types. When
