Return a matrix with the specified dimensions (m, n, …) whose elements are taken from the matrix A.
The elements of the matrix are accessed in column-major order (like Fortran arrays are stored).
The following code demonstrates reshaping a 1x4 row vector into a 2x2 square matrix.
reshape ([1, 2, 3, 4], 2, 2)
⇒ 1 3
2 4
Note that the total number of elements in the original matrix
(prod (size (A))) must match the total number of elements
in the new matrix (prod ([m n …])).
A single dimension of the return matrix may be left unspecified and Octave will determine its size automatically. An empty matrix ([]) is used to flag the unspecified dimension.
