distributed.sprandn

Create distributed sparse array of normally distributed pseudo-random values

Syntax

DS = distributed.sprandn(m,n,density)

Description

DS = distributed.sprandn(m,n,density) creates an m-by-n sparse distributed array with approximately density*m*n normally distributed nonzero double entries.

Examples

Create a 1000-by-1000 sparse distributed double array DS with approximately 1000 nonzeros. 

DS = distributed.sprandn(1000,1000,0.001);

Tips

When you use sprandn on the workers in the parallel pool, or in an independent or communicating job (including pmode), 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.
