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.
Input :

ranm(2,4)
Output :
[[27,-29,37,-66],[-11,76,65,-33]]
Input :
ranm(2,4,3)
Or input :
ranm(2,4,'rand(3)')
Output :
