Same codes and same results. But which one is faster? I captured screens in Turkish, so I just write results:

Matlab: 0.26349 seconds
Powershell v1.0: 3 seconds

But Matlab is $$$ and Powershell is Free!

I can wait 3 seconds more if I use a free product. So winner is Matlab but my choise is Powershell. Of course Powershell is not an advanced math program but it is quite good for basic math problems.
