Mupad vs Maple

I recently had a change to compare mupad in 2008b and maple in 2008a. It seems mupad has a problem or is slow or otherwise less compatible than maple. I wrote a function and ran it in both. 2008a took 36 seconds to complete processing and plot a graph. 2008b took about 6 times longer.

Can anyone say why mupad is slower? Is it a configuration problem, does it need more memory or is its straight up slower?

I am facing similar problems as well. subs function in 2008a, 2007b have bugs. 'syms' function hangs or takes a long time is a reported bug yet to be fixed. Somewhere I cam across that the mupad matlab interface is not well written.

I also need some solution to MATLAB being slow for symbolic maths. Can we get some input on this issue

need some suggestion.

a toolbox that I developed using matlab's symbolic maths runs very slow on the current version. my question is will user defined symbolic math functions run FASTER if it was created in MUPAD ?

I can only confirm that I have the same problem and when trying to compute some very long expression the latest r2009a (uses MuPad) is several orders of magnitude slower than r2008a (uses Maple).

If you have a copy of Maple, you can still use it to do symbolic work with MATLAB. They have a toolbox called the Maple Toolbox for MATLAB that lets you use the 2 softwares together. I downloaded it free from the Maplesoft website. All the work I did with the Maple version of the symbolic toolbox works too.
