Create Codistributed Randn Matrix

Create a 1000-by-1000 codistributed double matrix of randn values, distributed by its

second dimension (columns).

spmd(4)

C = randn(1000,'codistributed');

end

With four workers, each worker contains a 1000-by-250 local piece of C.

Create a 1000-by-1000 codistributed single matrix of randn values, distributed by its

columns.

spmd(4)

codist = codistributor('1d',2,100*[1:numlabs]);

C = randn(1000,1000,'single',codist);

end

Each worker contains a 100-by-labindex local piece of C.

Create gpuArray Rand Matrix

Create a 1000-by-1000 gpuArray of randn values with underlying class double:

G = randn(1000,'double','gpuArray');
