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

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);

      }
