speed comparison - Matlab vs C vs python vs perl

I had found C code to be around 150x faster than Matlab for my implementation of the Monte Carlo code in Matlab.

User time:        3 sec for the C program
elapsed_time =  453.2500 sec  for the Matlab program

This stackoverfloe discussion has some interesting points to make - use Matlab first to get correct results, then increase speed with C, beware of errors in C libraries.

These benchmarks show python to be 3x to 100x slower than C - so, translating from Matlab to python in search of speed gains may not make sense.

These benchmarks show perl having similar speeds as python for loops - so I needn't explore perl, either.
