I have heard many times that such languages as Python, C++, R and Matlab are popular in finance industry. As for the first three it is a clear choice since they are open source and non-proprietary, but using Matlab requires purchasing of license, so my question is can quant (or anyone else doing quantitative tasks) use another proprietary CAS or programming language like Mathematica for example? If not, why just Matlab?
