Argument Values Descriptions
'gpuArray'
Specifies gpuArray.
datatype
'double' (default),
'single'
Specifies underlying class of the array, i.e., the
data type of its elements.
R = randn(sz,'like',P) creates an array of randn values with the same type and
underlying class (data type) as array P.
R = randn(sz,datatype,'like',P) creates an array of randn values with the
specified underlying class (datatype), and the same type as array P.
C = randn(sz,codist) or C = rand(sz,datatype,codist) creates a codistributed
array of randn values with the specified size and underlying class (the default datatype
is 'double'). The codistributor object codist specifies the distribution scheme for
creating the codistributed array. For information on constructing codistributor objects,
see the reference pages for codistributor1d and codistributor2dbc. To use
the default distribution scheme, you can specify a codistributor constructor without
arguments. For example:
spmd
C = randn(8,codistributor1d());
end
C = randn(sz, ___ ,codist,'noCommunication') specifies that no interworker
communication is to be performed when constructing a codistributed array, skipping
some error checking steps.
C = randn(sz, ___ ,codist,'like',P) creates a codistributed array of randn
values with the specified size, underlying class, and distribution scheme. If either
the class or codistributor argument is omitted, the characteristic is acquired from the
codistributed array P.
Examples
Create Distributed Randn Matrix
Create a 1000-by-1000 distributed array of randn values with underlying class double:
D = randn(1000,'distributed');
