I understand that you require to convert your MATLAB source code to C# code. Unfortunately, MATLAB does not currently have the capability to directly generate C# code unlike C or C++. Hence to use MATLAB code as in C# you can consider the following options:
1) You can Build a .NET assembly using MATLAB Compiler SDK. The compiled applications use the MATLAB Runtime, a set of shared libraries that enables the execution of compiled MATLAB applications or components. More information on this can be found here: https://www.mathworks.com/help/releases/R2021b/compiler_sdk/dotnet_assemblies.html
2) Call a MATLAB function from a C# application, which acts as a client. More information on this workflow can be found here: https://www.mathworks.com/help/releases/R2021b/matlab/matlab_external/call-matlab-function-from-c-client.html
Hope this helps! Thanks.
