I developed a MATLAB function, and I'm looking for a way to call that function from another C# application and pass some parameters to it and get the results in the C# program.
I heard that I can use Dynamic Data Exchange (DDE) or COM objects, but have can I do it?
There is nice example in the MATLAB Central.
It shows three ways on how to communicate with MATLAB:
- COM
- MATLAB .NET Bulider
- MATLAB compiler
COM (I do not have any experience with it)
Cons: MATLAB is required to be installed on the target computer.
MATLAB .NET builder compiles your MATLAB code to the .NET assembly and you can use it directly.
Pros: MATLAB is not required to be installed on the target computer
Cons: It's expensive
MATLAB compiler compiles your MATLAB code into a C/C++ library or EXE file. You can use it through P/Invoke.
Pros: MATLAB is not required to be installed on the target computer
Cons: It's expensive, a lot of P/Invoke.
There is a third option: delegates. Starting MATLAB -> load .NET assembly -> execute .NET function with delegate handle to a MATLAB function.
There is a great example on this site on setting up everything. You can use MATLAB .NET deployment tool.
You need to
- Install MCR (Matlab Compiler Runtime).
- Deploy your Matlab function to .NET Assembly using Matlab Deploy Tool. This will create a .dll file.
- Add .dll reference inside your .NET project.
- Add reference to MATLAB.NET.
The advantage of this method is that the target machine does not require MATLAB to be installed, but on the downside the execution is quite expensive.
