The size of the matrix will be % @var{n} by @var{n}, with a density of values given by @var{d}. % @var{d} should be between 0 and 1. Values will be normally % distributed with mean of zero and variance 1. % % Note: sometimes the actual density may be a bit smaller than @var{d}. % This is unlikely to happen for large really sparse matrices. % % If called with a single matrix argument, a random sparse matrix is % generated wherever the matrix @var{S} is non-zero in its lower % triangular part. % @seealso{sprand, sprandn} % @end deftypefn
