matrix — reshape a vector or a matrix to a different size matrix
y=matrix(v,n,m) y=matrix(v,[sizes])
| v | : a vector, a matrix or an hypermatrix |
| n,m | : integers |
| sizes | : vector of integers |
| y | : a vector, a matrix or hypermatrix |
For a vector or a matrix with n x m entries, the command y=matrix(v,n,m) or similarily y=matrix(v,[n,m]) transforms the v vector (or matrix) into an nxm matrix by stacking columnwise the entries of v.
if one of the dimension m or n is equal to -1 it is automatically assigned to the quotient of size(v,'*') by the other dimension,
For an hypermatrix such as prod(size(v))==prod(sizes), the command y=matrix(v,sizes) (or equivalently y=matrix(v,n1,n2,...nm)) transforms v into an matrix or hypermatrix by stacking "columnwise" (first dimension is varying first) the entries of v. y=matrix(v,sizes) results in a regular matrix if sizes is a scalar or a 2-vector.
