GSoC 2016 project idea - implementation of ode15s

[Richard Crozier]

Dear List,

I have an idea for a GSoC project idea which I think would be very 
beneficial for Octave now that the ode* functions are in core. A major 
omission currently is ode15s which is a stiff differential solver which 
is very effective. The closest equivalent solver in odepkg is probably 
ode5r and, at least for the problems I solve this is much slower because 
the number of steps taken to solve the problem is far smaller with ode15s.

The documentation for ode15s can be found here:

http://uk.mathworks.com/help/matlab/ref/ode15s.html

Documentation on the implementation can be found in these references:

"The MATLAB ODE Suite", L. F. Shampine and M. W. Reichelt, SIAM Journal 
on Scientific Computing, 18-1, 1997

"Solving Index-1 DAEs in MATLAB and Simulink", L. F. Shampine, M. W. 
Reichelt, and J. A. Kierzenka, SIAM Review, 41-3, 1999.

I have access to these papers.

What I don't have is the skills or knowledge to mentor a project 
implementing the function. I would have the time and ability to help 
monitor progress and give general coding advice to the student.

Would anyone else be interested in mentoring this project?

Regards,

Richard
