    It's good for any kind of numeric mathematics, but particularly good at anything involving Matrices, including solving simultaneous equations. It's on the UCD computers under "Teaching Applications".

    You are the type of what the age is searching for, and what it is afraid it has found. I am so glad that you have never done anything, never carved a statue, or painted a picture, or produced anything outside of yourself! Life has been your art. You have set yourself to music. Your days are your sonnets.

    Yeah. It stands for MATrix LABoratory. It's also a programming language in it's own right, very similar to C, but has an awful lot of built-in functions - try coding up an FFT (Fast Fourier Transform) in C for example compared to calling the MATLAB FFT function!

    It can be kind of slow though since it's an interpreted langauge as opposed to a compiled language, such as C. The trick with it is to try to use matrices and vectors for as much as possible (often for loops can be replaced with vector and/or matrix operations).

    There are a couple of MATLAB clones, but the one I've used the most is the open source Octave system. It's free, so you can try it out for fun, and it's code-compatible for most things, but I have ran in to a few snags e.g. when working with Structures.

    Its on the DIT Bolton Street computer system and used to computer classes towards the final years of engineering degrees.

    I have mainly used it to solve differential equations, can be tricky at the start at get your head around it! Yet as the previous posts said once you get used to using matrices for everything its actually very quick!
