It sounds amazing!

I didn't know it did audio processing as well as math. You learn something new on PF every day

I use Mathematica extensively in my research. Most commonly for guessing the solutions to PDEs. I still do a lot by hand, though, such as finding Ricci tensors.

Actually I believe you can do audio and image processing in Mathematica, or at least you could write code to do so, just as you can in Matlab.

We have a site license for Mathematica 8, so I've installed it for free. :)

Isn't there an open-source alternative to Mathematica - a program that will do symbolic math instead of just numerical?

i have no license at all... :shy:

Do you use it? How well does it work if so?

I use Mathematica and have never used it, I just googled Mathematica open-source alternatives and that came up. This might help....http://www.calvin.edu/~rpruim/talks/Sage/2010-05-08-MAA/sagetalk.pdf

It seems the only open source app that comes close to Mathematica or Maple but even so they are in a different league- Going solely on reviews...

I've used Mathematica extensively for about 15 years working on a wide variety of problems. Currently I use it to study contour integration over multi-valued functions. For example, what does it look like to integrate over the inverse of a 12-degree polynomial? Well, one example is

[tex]\mathop\oint\limits_{\text{black}} \text{red}\; dz[/tex]

Jack you can't delete the attachment after you use the link...It has to stay attached.

Learning how to become really good and productive with any computer algebra system takes a very large investment of time so choose carefully. It is probably best to use what those around you, or those who you hope to be around, use and which you can get books to help you get started.

Hi guys. I did not think I deleted the link. Anyway, that figure is the real surface of the inverse of a particular polynomial. If we have [itex]w=a_0+a_1 z+\cdots+a_{12}z^{12}[/itex], then what is z in terms of w? Well, it's a 12-valued, complex-multi-valued function of w, [itex]z(w)[/itex], and it's real component in the domain of that plot is that figure.

But you can't draw it with built-in Mathematica functions. You have to code it yourself and I like writing graphics code and that is what I like best about Mathematica. The code I wrote to illustrate multi-valued functions is about 2000 lines of Mathematica code.

Let me try the attachment again. This time it's only the 4-cycle branch of the total figure showing the black path of integration over it:

where can I learn how to run monte carlo simulations online? I've always been curious about that.
