RESHAPE

Creates a new matrix from an existing matrix with dimensions you specified in the shape-descriptor array.

RESHAPE produces valid results for any matrix with any given shape dimensions, getting values from M in a cyclic fashion.

RESHAPE (M,S)

M	A matrix.
S	A shape-descriptor array. Can contain up to two dimensions.

The following example illustrates the use of the RESHAPE function:

Function	RESHAPE({1, 0, 0, 0}, {3, 3})
Result	{[1, 0, 0], [0, 1, 0], [0, 0, 1]}

Because scalars are coerced into 1x1 matrices, you can also have the following:

Function	RESHAPE(1, {2, 2})
Result	{[1, 1], [1, 1]}
