Composite

Access nondistributed variables on multiple workers from client

Constructor

Composite

Description

Variables that exist on the workers running an spmd statement are accessible on the client as a Composite object. A Composite resembles a cell array with one element for each worker. So for Composite C:

C{1} represents value of C on worker1
C{2} represents value of C on worker2
etc.

spmd statements create Composites automatically, which you can access after the statement completes. You can also create a Composite explicitly with the Composite function.

Methods

existCheck whether Composite is defined on workers
subsasgnSubscripted assignment for Composite
subsrefSubscripted reference for Composite

Other methods of a Composite object behave similarly to these MATLAB® array functions:

disp, displayDisplay Composite
endIndicate last Composite index
isemptyDetermine whether Composite is empty
lengthLength of Composite
ndimsNumber of Composite dimensions
numelNumber of elements in Composite
sizeComposite dimensions

Introduced in R2008b
