matrix Scilab Group Scilab Function matrix
NAME
matrix - reshape a vector or a matrix to a different size matrix
CALLING SEQUENCE
y=matrix(v,n,m)
y=matrix(v,[sizes])
PARAMETERS
v : a vector, a matrix or an hypermatrix
n,m : integers
sizes : vector of integers
y : a vector matrix or hypermatrix
DESCRIPTION
For a vector or a matrix with n x m entries 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),y=matrix(v,sizes)
(or equivalently y=matrix(v,n1,n2,...nm)) transforms v into an matrix
or hypermatrix by stacking columnwise the entries of v.
y=matrix(v,sizes) results in a regular matrix if sizes is a scalar or a
2-vector.
