programming with matlab and .NET C#

Hello ,all!

I want to pack the nlinfit method as a Class(.NET assembly) so I can use in my C# application. But there is a problem:

There are four parameters in nlinfit method:( X,Y,MODELFUN,BETA0 ) . Among them X Y and BETAO all are matrix(Class Array can be transform to Class MWArray in C#),but parameter MODELFUN is a funtion in matlab. What does function in matlab means in .NET?

I would suggest what I think is the easiest way:

If MODELFUN is a matlab function handle, use inside your "matlab method" the command str2func , in order to transform a string into a function handle

function out = mynlinfit(X,Y,MODELFUN,BETA0)
    MODELFUN2 = str2func(MODELFUN); % MODELFUN  is a string. e.g: '@(x) cos(x)'
                                    % MODELFUN2 is a function handle.
    out = nlinfit(X,Y,MODELFUN2,BETA0);

Now, MODELFUN2 is a function handle (which can be used in the original nlintfit), while your method's input MODELFUN is a string, which you don't need to cast in C#, as .NET strings are directly interpreted by matlab.

Hope it helps.

Thank you so much! I think I have got your point and it's possibly the easiest way to handle this question!

In my case, the MODELFUN is not a matlab function but a function in C#. How could I transfer this function from C# to Matlab? Now I want to pack the gaoptimset method:( FINESSfCN,nvars,...)in the matlab toolbox as a Class(.NET assembly) so I can use in my C# program, but FINESSfCN is a function in my C# program. What should I do to transfer the function in the C# to the gaoptimset method?
