Matlab and Monte Carlo simulations
This example shows the use of python to generate many matlab jobs. Each of these matlab jobs is a monte carlo simulation with different parameters as written about here http://en.literateprograms.org/Monte_Carlo_simulation_%28Matlab%29#chunk%20def:simplest_monovariate_montecarlo.
