How do I call the nlinfit() function from VB.NET ?

Hi, I am a student and quite a novice with MATLAB. I have a research project where I need to fit a Lorentz function to data. The original code for this research project has been written in VB.NET by a previous student.

I'd like to somehow include the non linear fitting function nlinfit() into the VB.NET project. Is there a way in MATLAB to create a file/library that I can then include in the VB.NET project ? I assume the process involves some sort of compilation of the .m file ?

My programming skills are not slick, and so there is no possibility of re writing the entire project in MATLAB just to access the nlinfit function.

Any help would be greatly appreciated.

Thanks, Ryan
