Hi,
I joined my Ph.D. from August 2018 in Observational Cosmology. In starting I'm working with cosmological models with different cosmological parameters. I have to find out the values of these parameters using the MCMC technique. For this people are working with python for MCMC using emacs. But I want to do it using C-Code. Because I am much familiar with it. I have done integration using the Monte Carlo method. And also generated random number from a Gaussian distribution with a box-muller method.
 Now I'm trying to do go further to estimate unknown parameters using MCMC and also plot correlation between each parameter. So my aim is to find these plot of this link:-    https://ibb.co/cqWyhA

Now my query is that is it right choice to do work with C-code for MCMC?  Please share your experience with MCMC.
