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. |

Description |
TypeError |
If sizes does not contain solely integers |
DimensionError |
If the product of the new dimension sizes does not equal that of the old ones |
Examples
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]]
