Create Codistributed Identity Matrix

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

dimension (columns).

spmd(4)

C = eye(1000,'codistributed');

end

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

Create a 1000-by-1000 codistributed uint16 identity matrix , distributed by its columns.

spmd(4)

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

C = eye(1000,1000,'uint16',codist);

end

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

Create gpuArray Identity Matrix

Create a 1000-by-1000 gpuArray identity matrix of underlying class uint32:

G = eye(1000,'uint32','gpuArray');
