Re: pdepe

[Nikola Yuroukov]

Hi Carlo,

Sorry for the late reply. Soo... it seems like pdepe is a tough nut to crack. I have some ideas, but I have not yet come close to anything that would give us a stable and robust implementation.

So I'd like to start on something else and put the pdepe on standby for now. Do you have anything else I could help out with? I'm from a maths and CS background, but could also work on GUI and web.

Regards,

Nikola

If you plan to make an m-file-only implementation (which I do reccommend)
I would suggest you start working on this as an indipendent code, we
can then move it into Octave later.

If you have a publicly visible repository for your code, e.g. on
bitbucket or github, it would help to see your code while you work
on it, in order to give more detailed advice.

The algorithm described in that project is not the most modern
nor the most commonly used, the main reason for having that function
in Octave is to allow to "liberate" existing m-file code that depends
on it.

For this reason, the main requirement is to make this function as
much as possible compatible to the Matlab version:

www.mathworks.com/help/matlab/ref/pdepe.html

The algorithm is described in detail in this paper:

[1] Skeel, R. D. and M. Berzins, "A Method for the Spatial Discretization of Parabolic
Equations in One Space Variable," SIAM Journal on Scientific and Statistical Computing,
Vol. 11, 1990, pp.1–32.

While working on this project, please consider that, while it is OK
to read public documentation for Matlab functions, you should
NEVER LOOK AT THEIR SOURCE CODE.
