its large but its not the entire scientific community. I used to be a matlab user, my entire phd thesis work was all in matlab, we were in medical imaging. Then I left to work in industry in finance and we use python numpy scipy for all our work and its much better than matlab. R, Fortran, C/C++/Java are also highly represented in scientific work.
