Random matrix : ranm randMat randmatrix

### 5.42.3 Random matrix : ranm randMat randmatrix

ranm or randMat or randmatrix takes as argument an integer n or two integers n,m and optionally a third argument, either an integer k or the quoted name of a random distribution law (see also 5.25.25, 5.38.36 and ??).
ranm returns a vector of size n or a matrix of size n× m containing random integers uniformly 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.
