randomMutableMatrix(ZZ,ZZ,RR,ZZ) -- a random mutable matrix of integers

Synopsis

Usage:
randomMutableMatrix(nrows,ncols,zerof,max)
Function: randomMutableMatrix
Inputs:
- nrows, an integer
- ncols, an integer
- zerof, a real number, between 0 and 1
- max, an integer
Outputs:
- a random mutable nrows by ncols matrix of integers. The absolute value of the entries is bounded by max, and the frequency of entries equal to zero is given by zerof.
Optional inputs:
- Dense => ...,
