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
• Optional inputs:

  • Dense => default value false, whether the encoding of the matrix should be dense or not: see MutableMatrix
• Outputs:

  • a mutable matrix, a random mutable nrows by ncols matrix of integers. The absolute value of the entries is less than max, and the frequency of entries equal to zero is given by zerof.
