    mathematical Libraries

    Hi. I work above all with Matlab (in C I am a beginner), but i know that a well programmed C code is faster than a Matlab one. So, is there any mathematical library which contains functions similar to Matlab functions (like gradient, fft, fspecial, filter2, ...)? Or does somebody know any way to convert a .m code to an optimum .c or .cpp?
    Because i may compare 2 algorithms, Matlab one is faster (in theory), but in Matlab the algorihm developed in C (and convert to mex to compare) is faster.
    Thank you.

    A couple mathematical libraries are LAPACK/BLAS for linear algebra, and GMP for ... well, pretty much everything. Depending on your setup you may already have the first installed.

    Edit: I said GMP but meant GSL. Sorry.
