Create Codistributed NaN Matrix

Create a 1000-by-1000 codistributed double matrix of NaNs, distributed by its second

dimension (columns).

spmd(4)

C = NaN(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 NaNs, distributed by its columns.

spmd(4)

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

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

end

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

Create gpuArray NaN Matrix

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

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