codistributed.sprandn

Create codistributed sparse array of uniformly distributed pseudo-random values

Syntax

CS = codistributed.sprandn(m, n, density)

CS = sprandn(n, codist)

Description

CS = codistributed.sprandn(m, n, density) creates an m-by-n sparse

codistributed array with approximately density*m*n normally distributed nonzero

double entries.

Optional arguments to codistributed.sprandn must be specified after the required

arguments, and in the following order:

• codist — A codistributor object specifying the distribution scheme of the resulting

array. If omitted, the array is distributed using the default distribution scheme.

For information on constructing codistributor objects, see the reference pages for

codistributor1d and codistributor2dbc.

• 'noCommunication' — Specifies that no interworker communication is to be

performed when constructing the array, skipping some error checking steps.

CS = sprandn(n, codist) is the same as CS = codistributed.sprandn(n,

codist). You can also use the optional arguments with this syntax. To use the default

distribution scheme, specify a codistributor constructor without arguments. For example:

spmd

CS = codistributed.sprandn(8, 8, 0.2, codistributor1d());

end
