Sundials solvers in Matlab

I am getting following error

" Error in IDASolve (line 64)

[varargout{:}] = idm(mode,tout,itask); "

IDASolve is a matalb function with

mode = 20;
if nargin ~= 2
    error('Wrong number of input arguments');
end
if nargout < 3 || nargout > 5
    error('Wrong number of output arguments');
end
varargout = cell (nargout, 1);
[varargout{:}] = idm(mode,tout,itask);

How do I rectify this. Thanks

Is it a MATLAB function in a toolbox (which one?), or a built-in function? Or is a function you wrote yourself, or someone else wrote, in the MATLAB programming language? Where did you get it?

How did you call IDASolve? Meaning, what were the values of the arguments you sent in to it?

What was the actual error? There should be a message in addition to the line of code that threw the error.

If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:

which IDAsolve -all

'IDAsolve' not found.

which idm -all

'idm' not found.

Since both idm and IDAsolve do not seem to exist as part of MATLAB or in any toolbox, they must be functions you wrote. Or they may be code someone gave to you, or you found it somewhere. We don't know, and we cannot see that code.

So, how do you fix it? Learn to use the debugger. Write better code. If you want more useful help, then you need to show the full code, not just a tiny unexecutable fragment.

The solver seems to be part of SimBiology, but the information given about the error is far too vague to give advice.

FYI as of release R2024a, several of the SUNDIALS solvers are available in MATLAB proper via the ode object. See the Release Notes.

@Image Analyst please find the code attached.

I am using sundials 2.6.2 version alongwith the sundialsTB toolbox to integrate the solvers available in sundials in order to solve the Differential Algebraic Equations.

IDASolve is a user defined function inside of the sundialsTB toolbox.

I am aware that the latest versions of Matlab contains the SUNDIALS solvers but I still wanted to use the sundials toolbox.

The above error I am getting when I run the DAE_IDAS.m file (attached file).
