24 Sep 2014 GPUBench Compare GPUs using standard numerical benchmarks in MATLAB. Author: Parallel Computing Team R., Alex

@Fabio: This is on a Macbook Pro Late 2013, 2.3 Ghz, 16 GB. See last two rows. Seems only the FFT double-precision is faster than the CPU (about twice as fast). \ and * are much slower. Pretty crippled performance ...
Apple should have used the Quadro K1100M (same physical chip as the 750M without the crippled double-precision). From the looks of it, it's not really worth the effort of coding for the GPU on the MBP with 750M. You can just stick with the CPU. Problem is that if you want to buy the MBP without the 750M but with the same CPU, you end up paying the same price (at least that was the case back in May when I bought it).

03 Sep 2014 Worker Object Wrapper Simplifies managing resources such as large data within PARFOR loops and SPMD blocks Author: Parallel Computing Team Ellis, Edric

@Dan, try replacing line 136 with the following:

Map = containers.Map(uint32(0), [], 'UniformValues', false);

which is the R2009a syntax.

@Edric - Hi. Thank you for responding so quickly! I am running a fairly old version of MATLAB, MATLAB 7.8.0 (R2009a).

When I run:
>> containers.Map( 'KeyType', 'uint32', 'ValueType', 'any' )

I get the same error I got before:

??? No constructor 'containers.Map' with matching signature found.

Thanks!
