# Function reshape Reshape a multi dimensional array to fit the specified dimensions ## Syntax ```js math.reshape(x, sizes) ``` ### Parameters Parameter | Type | Description --------- | ---- | ----------- `x` | Array | Matrix | * | Matrix to be reshaped `sizes` | number[] | One dimensional array with integral sizes for each dimension. One -1 is allowed as wildcard, which calculates this dimension automatically. ### Returns Type | Description ---- | ----------- * | Array | Matrix | A reshaped clone of matrix `x` ## Examples ```js math.reshape([1, 2, 3, 4, 5, 6], [2, 3]) // returns Array [[1, 2, 3], [4, 5, 6]] math.reshape([[1, 2], [3, 4]], [1, 4]) // returns Array [[1, 2, 3, 4]] math.reshape([[1, 2], [3, 4]], [4]) // returns Array [1, 2, 3, 4] const x = math.matrix([1, 2, 3, 4, 5, 6, 7, 8]) math.reshape(x, [2, 2, 2]) // returns Matrix [[[1, 2], [3, 4]], [[5, 6], [7, 8]]] math.reshape([1, 2, 3, 4], [-1, 2]) // returns Matrix [[1, 2], [3, 4]] ``` ## See also [size](size.md), [squeeze](squeeze.md), [resize](resize.md)
