I've been trying to run the example here: http://www.mathworks.co.uk/support/tech-notes/1600/1608.html#Section_5
but I continually get this error->

System.Runtime.InteropServices.COMException
at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)
at MLApp.MLAppClass.GetWorkspaceData(String Name, String Workspace, Object& pdata)
at MyMatlabService_test.Service1.ProcessXML(String aInputXML) in C:\Inetpub\wwwroot\EDASH_Data\MyMatlabService_test\MyMatlabService_test\Service1.asmx.vb:line 27

line 27 being: myMATLAB.GetWorkspaceData("transOut", "base", outputXML)

I'm using Matlab R2010a, VS 2008, IIS 5.1

Any help would be appreciated!

It looks like the line:
myMATLAB.PutWorkspaceData("transIn","base", , aInputXml);

has a typo (the extra , ?)

Ashish,

Thanks for the note, I did address that initially after looking at the sample code.

You do have a variable transOut in your base workspace right? (and a
function TxRequest on the path which creates it?)

If you are debugging, and have teh MATLAB automation server session open.
You could try executing simple commands and manually inspect the base
workspace in the server session (say using whos) to ensure that the
connection works.

Ashish,

I'm new to Matlab and really just need to execute a function from the .NET COM interface.
I'm in need of some simple guidance I thought the Mathworks example could provide.
If I had a function (addtwo.m):
-function addtwo(x,y)
-%adds two numbers, vectors, etc
-% print the result of x + y
- x + y
-end

How do I call that in the .NET COM, similar to the example Mathworks provides?
