R2012b
6-4
• mrdivide is now fully supported, and is no longer limited to accepting only scalars
for its second argument.
• sparse is now fully supported for all distribution types.
This release also offers improved performance of fft functions for long vectors as
distributed arrays.
Detection of MATLAB Distributed Computing Server clusters that are
available for connection from user desktops through Profile Manager
You can let MATLAB discover clusters for you. Use either of the following techniques to
discover those clusters which are available for you to use:
• On the Home tab in the Environment section, click Parallel > Discover Clusters.
• In the Cluster Profile Manager, click Discover Clusters.
For more information, see Discover Clusters.
gpuArray Class Name
The object type formerly known as a GPUArray has been renamed to gpuArray. The
corresponding class name has been changed from parallel.gpu.GPUArray to the shorter
gpuArray. The name of the function gpuArray remains unchanged.
Compatibility Considerations
You cannot load gpuArray objects from files that were saved in previous versions.
Code that uses the old class name must be updated to use the shorter new name. For
example, the functions for directly generating gpuArrays on the GPU:
Previous version form New version form
parallel.gpu.GPUArray.rand
parallel.gpu.GPUArray.ones
etc.
gpuArray.rand
gpuArray.ones
etc.
Diary Output Now Available During Running Task
Diary output from tasks (including those of batch jobs) can now be obtained while
the task is still running. The diary is text output that would normally be sent to the
