|
| 12 | * Calculate the exponent of a value.
|
| 13 | * For matrices, the function is evaluated element wise.
|
| 14 | *
|
| 15 | * Syntax:
|
| 16 | *
|
| 17 | * math.exp(x)
|
| 18 | *
|
| 19 | * Examples:
|
| 20 | *
|
| 21 | * math.exp(2) // returns number 7.3890560989306495
|
| 22 | * math.pow(math.e, 2) // returns number 7.3890560989306495
|
| 23 | * math.log(math.exp(2)) // returns number 2
|
| 24 | *
|
| 25 | * math.exp([1, 2, 3])
|
| 26 | * // returns Array [
|
| 27 | * // 2.718281828459045,
|
| 28 | * // 7.3890560989306495,
