[sundials-users] Using Sundials CVODE solver in MATLAB

[Deepa]

Dear All,

I am new here.

I want to use Sundials CVODE solver in MATLAB and I am not sure if there are existing

functions that can be used in MATLAB by specifying the ode_solver as Sundials.

I have downloaded CVODE-6.6.0 from here https://computing.llnl.gov/projects/sundials/sundials-software.

But I am not sure how to proceed further. Suggestions will be of great help.

Thanks a lot for your kind attention,

Deepa

Hello Deepa,

 

SUNDIALS does not have a current MATLAB interface. SUNDIALS v2.5.0 was the last version with a supported MATLAB interface.

 

Cheers,

Cody

Hello Deepa,

while sundials itself doesn't have a MATLAB interface,

there exist an open-source MATLAB 2 C compiler called QSPcc that can be used to solve systems of ODE using the CVode family of functions.

With an additional (not open-source) module, you can also auto-generate a MEX file that can be used from MATLAB.

Hello Cody

Thank you. Could you please suggest if there are alternate ways to use CVODE in MATLAB 

i.e. using a C++ wrapper? Are there some examples that I can look at?

Thanks a lot for your kind attention, 

Deepa

It looks like Danilo has suggested a nice looking alternative for wrapping the C code.  I am not personally aware of other solutions for MATLAB, but I am sure there are some.

Dear Dalino,

Awesome! Thank you so much for introducing me to QSPcc. 

I would like to try the second method

i.e. generate the MEX code and call the CVODE solver from MATLAB.

Could you please let me know if I should first use the cvode C code and generate the MEX file via QSPcc?

Could you please direct me to an example on how to proceed? I'm sorry these are a bit new to me.
