a resource utilization matrix (rows = species, columns = discrete
resource states) filled with non-negative real numbers.
Value
Returns a random utilization matrix with the same dimensions as the
input matrix.
Details
The resource utilization matrix (rows = species, columns = discrete
resource categories) may include zeroes, but no negative numbers or missing
values. Relative resource within a species is first calculated, so the rows
need not sum to 1.0.
