I'm new to COM automation using MATLAB and VB.NET so I made a simple program that adds two number and display the result in the textbox. The addition is done using MATLAB. Every time I run the program, the returned value in the textbox is this: * _ ??? Undefined function or variable 'a'. _ *
My MATLAB code is this:
function out = addMe(a,b)
out = a + b;
end
My VB code is this:
Imports Add
Public Class Form1
Dim a As Integer
Dim b As Integer
Dim MATLAB As Object
Dim result As String
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
a = 5
b = 10
MATLAB = CreateObject("MATLAB.Application")
result = MATLAB.Execute("cd C:\Users\Elvin Gentiles\Desktop\Program")
result = MATLAB.Execute("out = addMe(a,b)")
TextBox1.Text = result
End Sub
End Class
I hope you can help me. Thanks

You have not passed in your VBA variables a and b to the Matlab COM environment.
