Call MATLAB Function From C#

Call MATLAB Function from C# Client This example shows how to call a user-defined MATLAB ® function, myfunc, from a C# application. Create a MATLAB function, myfunc, in the folder c:\temp\ example. function [x,y] = myfunc(a,b,c) x = a + b; y = sprintf('Hello %s',c); Create the C# application. using System; using System.Collections.Generic; using System.Text; namespace ConsoleApplication2 { class Program { static void Main(string[] args) { // Create the MATLAB instance MLApp.MLApp matlab = new MLApp.MLApp(); // Change to the directory where the function is located matlab.Execute(@"cd c:\temp\example"); // Define the output object result = null; // Call the MATLAB function myfunc matlab.Feval("myfunc", 2, out result, 3.14, 42.0, "world"); // Display result object[] res = result as object[]; Console.WriteLine(res[0]); Console.WriteLine(res[1]); Console.ReadLine(); } }
