Examples

Create Distributed Ones Matrix

Create a 1000-by-1000 distributed array of ones with underlying class double:

D = ones(1000,'distributed');

Create Codistributed Ones Matrix

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

dimension (columns).

spmd(4)

C = ones(1000,'codistributed');

end

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

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

spmd(4)

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

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

end

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

Create gpuArray Ones Matrix

Create a 1000-by-1000 gpuArray of ones with underlying class uint32:

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