Create distributed sparse array of normally distributed pseudo-random values
DS = distributed.sprandn(m,n,density)
DS = distributed.sprandn(m,n,density) creates an
m-by-n sparse distributed array with
approximately density*m*n normally distributed nonzero double
entries.
Create a 1000-by-1000 sparse distributed double array DS with
approximately 1000 nonzeros.
DS = distributed.sprandn(1000,1000,0.001);
When you use sprandn on the workers in the parallel pool, or in
an independent or communicating job, each worker sets its random generator seed to a
value that depends only on the labindex or task ID. Therefore,
the array on each worker is unique for that job. However, if you repeat the job, you
get the same random data.
