codistributed.speye

11-35

CS = speye(m, n, codist) and CS = speye([m, n], codist) are the same as

CS = codistributed.speye(m, n) and CS = codistributed.speye([m, n]),

respectively. You can also use the optional arguments with this syntax.

Note To create a sparse codistributed array of underlying class logical, first create an

array of underlying class double and then cast it using the logical function:

CLS = logical(speye(m, n, codistributor1d()))

Examples

With four workers,

spmd(4)

CS = speye(1000, codistributor())

end

creates a 1000-by-1000 sparse codistributed double array CS, distributed by its second

dimension (columns). Each worker contains a 1000-by-250 local piece of CS.

spmd(4)

codist = codistributor1d(2, 1:numlabs);

CS = speye(10, 10, codist);

end

creates a 10-by-10 sparse codistributed double array CS, distributed by its columns. Each

worker contains a 10-by-labindex local piece of CS.
