    matrix multiplication

    Hey all,
    I'm completely new to anything concerning computers so am lost. I would like to multiply two matrices in C by calling some built-in function of some library. How do I find the right library and function, and how do I find the proper format to past the matrices to the function?
    Sorry for such a stupid question, need to start somewhere..
    Have a nice day!

    Most people start with a web search - say https://encrypted.google.com/search?...tion+library+c
    Now "right" library is entirely subjective. You read about some of them, maybe even try a few to see how it goes, and be prepared to go back a step or two if your decision doesn't pan out.

    Read the manual pages for the library you've chosen.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
