# 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)
