It is possible to call MATLAB files from a Visual Basic application using ActiveX features.

Here is an example:

Dim MatLab As Object

Private Sub Command1_Click()

Dim Result As String 

Dim MReal(1, 3) As Double 

Dim MImag() As Double

Set MatLab = CreateObject("Matlab.Application")

'CALLING MATLAB FILE FROM VB

Result = MatLab.Execute("cd D:\MATLABR12\work\alltest") 

Result = MatLab.Execute("myfile") 

'OTHER THINGS THAT CAN BE DONE

Result = MatLab.Execute("surf(peaks)") 

Result = MatLab.Execute("a = [1 2 3 4; 5 6 7 8;]") 

Result = MatLab.Execute("b = a + a ")

Call MatLab.GetFullMatrix("b", "base", MReal, MImag)

End Sub

For more information, refer to Chapter 7 of the MATLAB External Interface/API User's Guide.
