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.
