MATLAB: Is there an example on how to use FEVAL from C# code

activatorccallingfevalMATLAB

I would like to call MATLAB from my C# code and to use the FEVAL method. Do you have an example on how I can perform that?

Below is an example showing the use of FEVAL from C# code:
add these two lines at the beginning
using System;
using System.Reflection;
      // Create or get an instance of MATLAB
      Type matlabType = Type.GetTypeFromProgID("Matlab.Application");
      object matlab = Activator.CreateInstance(matlabType);
      // Object[] parameters = new Object[] { functionName, nargout, Result, arg1, arg2, ... argN };
      Object[] parameters = new Object[] { "strcat", 1, null, "Hello", " World!" };
      // Make 3rd parameter (the return value) be passed by reference
      ParameterModifier mods = new ParameterModifier(parameters.Length);
      mods[2] = true;
      try
      {
          // Call Feval to evaluate the result of "strcat" function 
          matlabType.InvokeMember("Feval",
                                  BindingFlags.InvokeMethod,
                                  null,
                                  matlab,
                                  parameters,
                                  new ParameterModifier[] { mods },
                                  null,
                                  null);
          // Get the return value
          object Result = ((object[])parameters[2])[0];
          // Print the return value
          Console.WriteLine(Result);
      }
      catch (TargetInvocationException e)
      {
          Console.WriteLine(e.Message);
      }
