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 1.24.25, 1.37.36 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.
