I haven't tried it for pde1d.m because I was not able to build pde1d yet
but it works for any mex file I tried:

- let function "fun" be defined in file "fun.mex"
- let file "fun.m" contain a docstring and a demo block
- let both be in the path

typing "help fun" displays the docstring from "fun.m"
typing "demo fun" runs the demo from "fun.m"

pde1d is not a builtin function, it is a MEX file, so I don't think
this is relevant for the case at hand.

Anyway, if you have a builtin function defined in a C++ file named 
"pippo.cc" and "pippo.cc" is in your path, typing 

 demo pippo

or

 demo pippo.cc

will  run the demo blocks inside "pippo.cc"

You can try this with the attached file.

that's because maybe lsode has no demos?

c.

pippo.cc
