MATLAB users with a taste for GPU computing now have a perfect reason to move up to the latest version. Release R2010b adds native GPGPU support that allows user to harness NVIDIA graphics processors for engineering and scientific computing. The new capability is provided within the Parallel Computing Toolbox and Distributed Computing Server.
[Editor's Note: as pointed out in the comments by John Melanakos (from Accelereyes), it may be worth checking out how MATLAB 2010b GPU support currently compares to Accelereyes Jacket.]
