> The {{rand(...)}} function has a {{sparsity}} parameter that allows one to specify the desired sparsity of the generated matrix as in
> {code}
> X = rand(rows=10, cols=20, min=0, max=1, pdf=”uniform”, sparsity=0.2)
> {code}.
> Currently, the {{sparsity}} parameter only accepts {{Literal}} inputs, i.e. hard-coded double values, or variables that are themselves hard-coded double values.  It would be better to allow an expression that evaluates to a double value, such as the following, simple, contrived example:
> {code}
> s = log(0.2)
> X = rand(rows=10, cols=20, min=0, max=1, pdf=”uniform”, sparsity=s)
> {code}.
