Distributed Array Support

Newly Supported Functions

The following functions are enhanced to support distributed arrays, supporting all forms

of codistributor (1-D and 2DBC):

arrayfun

cat

reshape

Enhanced mtimes Support

The mtimes function now supports distributed arrays that use a 2-D block-cyclic (2DBC)

distribution scheme, and distributed arrays that use 1-D distribution with a distribution

dimension greater than 2. Previously, mtimes supported only 1-D distribution with a

distribution dimension of 1 or 2.

The mtimes function now returns a distributed array when only one of its inputs is

distributed, similar to its behavior for two distributed inputs.

Compatibility Considerations

In previous releases, mtimes returned a replicated array when one input was distributed

and the other input was replicated. Now it returns a distributed array.

Enhanced parfor Support

Nested for-Loops Inside parfor

You can now create nested for-loops inside a parfor-loop, and you can use both the

parfor-loop and for-loop variables directly as indices for the sliced array inside the

nested loop. See Nested Loops.

Enhanced Support for Microsoft Windows HPC Server

Support for 32-Bit Clients

The parallel computing products now support Microsoft Windows HPC Server on 32-bit

Windows clients.
