Random matrix : ranm randMat randmatrix

### 2.41.3 Random matrix : `ranm randMat randmatrix`

`ranm` or `randMat` or `randmatrix` takes as argument an integer n or two integers n,m and optionnally a third argument, either an integer k or the quoted name of a random distribution law (see also 2.24.25, 2.37.36 and ??).
`ranm` returns a vector of size n or a matrix of size n× m containing random integers uniformally distributed between -99 and +99 (default), or between 0 and k−1 or a matrix of size n× m containing random integers according to the law put between quotes.
Input :
