How to reproduce MATLAB's normal distribution random numbers?

I'm porting a project from MATLAB to Python and it turns out that while uniform distribution random generator are identical in NumPy and MATLAB, the numbers for normal distribution are slightly different. After some googling I've found out that the reason is different algorithms of transformation from uniform to normal distribution. MATLAB uses Ziggurat algorithm by default and NumPy uses Box-Muller if I'm not mistaken.


Our MATLAB project uses Phased Array Toolbox, so there's no way to insert our own generator into it.


Is there any way to reproduce MATLAB's normal distribution random generator in Python or C/C++?
