MATLAB: Is the VBA code in the “Spectral Analysis Example” in the documentation for MATLAB Builder for .NET 2.0 (R2006a) correct

The VBA code in the “Spectral Analysis Example” does not look correct. The line

Public theUtil as MWUtil object

does not appear to be the correct syntax for creating an MWUtil object.

Best Answer

The documentation for “Spectral Analysis Example” in MATLAB Builder for .NET 2.0 (R2006a) has been fixed in MATLAB Builder for .NET 2.1 (R2006b).

If you are using MATLAB Builder for .NET 2.0, change the line

Public theUtil as MWUtil object

to read:

Public theUtil as MWUtil

MATLAB: When passing “varargin” to a deployed Builder for Excel or Builder for .NET generic COM component, how to pass an empty “varargin” from VBA

This change has been incorporated into the documentation in Release 2009a (R2009a). For previous releases, read below for any additional information:

An empty "varargin" be passed in from VBA code as "Null". For example, suppose your MATLAB function signature is:

function b = foo(a,varargin)

VBA code which calls this deployed function, for an imaginary COM component named "mycomponent" containing a class "myclass" and versioned 1.0, with an empty varargin is:

 Dim aClass As Object
 Dim b As Variant
 Dim a As Variant
 'Initialize b here
 'Initialize a here
 aClass = CreateObject("mycomponent.myclass.1_0")
 Call aClass.foo(1,b,a,Null)

MATLAB: Can I use a COM object and a .NET object, both created using MATLAB Builder for .NET 2.0 (R2006a), in the Visual Studio project

It is possible to use a COM object and a .NET object - both generated with MATLAB Builder for .NET 2.0 (R2006a) - in the same project / program in Visual Studio.

If you have code that was earlier compiled into a COM object using MATLAB Builder for COM, you can now compile it into a COM object using MATLAB Builder for .NET. You can then include the .NET object and the COM object in the same program and be able to invoke the methods in your Visual Studio application.

The attached ZIP-file contains

a. A Visual Studio project written in C#

b. 2 MATLAB files - foo.m and bar1.m, used to generate

c. A COM object named foocomponent

d. A .NET object named foo2component

e. A .NET object named bar1component

In order to build and test this application, perform the steps given below using the files extracted from the attached ZIP-file:

1. Execute

mbuild -setup

at the MATLAB command prompt and select a supported C/ C++ compiler such as Microsoft Visual Studio 2005. Note that the LCC compiler cannot be used to build the components.

2. Launch DOTNETTOOL by typing

dotnettool

at the MATLAB command prompt.

3. Create a new project by selecting "File -> New Project" menu item and enter the component name 'foocomponent'. Accept the default class name and project settings.

4. Once you are returned to the MATLAB Builder window, highlight the component, click the "Add File" button and add foo.m

5. Select "Build -> COM object" menu item to build the COM object.

6. Follow steps 3-5 to generate the two .NET objects (use bar1.m for bar1component and foo.m for foo2component)

7. Open 'ConsoleApplication1' in Visual Studio.

8. In the Solution Explorer tab, right-click on 'ConsoleApplication1' and choose "Add Reference...". Add references to the above 3 components as well as to MWComUtil.

9. Select the "Build -> Build Solution" from the menu and then execute the application. You should see the words 'foo' and/ or 'bar' displayed upon successful execution.
