Chira,

I lke this project proposal, I would be interested in mentoring (or rather 
co-mentoring) on it.

As you also stated I think it should have lower priority with implementation of 
ode15s, 
because it is not a functionality for which there as much demand. 

Definitely an implementation of this feature should go iinto odepkg and not in 
core-Octave.

That said, I do encourage you to submit an application for GSOC about this.

The first point to investigate before starting development would be what is the 
state of
algorithms for computing matrix exponential in Octave and how that compares to 
Matlab.

I know there is another project being considered about matrix functions and I 
am not fully
aware of its state of advancement but I have seen that discussed on the list 
recently, I suggest you
look at those discussion threads.
