matrix

reshape a vector or a matrix to a different size matrix

Calling Sequence

y=matrix(v,n,m)
y=matrix(v,[sizes])

Arguments

v

a vector, a matrix or a hypermatrix

n,m

integers

sizes

vector of integers

y

a vector, a matrix or hypermatrix

Description

For a vector or a matrix with n x m entries, the command y=matrix(v,n,m) or similarly 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 a 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.

Examples

a=[1 2 3;4 5 6]
matrix(a,1,6)
matrix(a,1,-1)
matrix(a,3,2)
