Effect of GPU computing on speed in MATLAB

Hello Dears 

I started to evaluate effects of GPU & Parallel computing on MATLAB code runtime.

My system is a laptop from dell company(XPS15 L502X) and its configuration is:

CPU: Intel i7 2630QM

GPU: Nvidia GT540M

Its CPU and GPU are high end and can be good testbench.

My MATLAB is R2014a.

First section is devoted to GPU computing effect on code runtime.

There are many computations in MATLAB and can be evaluated as test bench.

It is suitable to start with matrix inverse computation.

I wrote a code to evalute matrix inversion runtime in MATLAB on both CPU and GPU.

I also iterated this code 100 times to get an accurate results.

You Can see the resaults:
