MATLAB Excel Builder

Creating a Project

To begin project creation, enter the MATLAB command mxltool at the command line. The MATLAB Excel Builder main window appears.

For a complete description of the features available from this window, see Graphical User Interface Menus.

Select File -> New Project on this window to view the New Project Settings dialog box.

Component name denotes the name of the DLL created later in the build process. After you enter the component name, the GUI automatically enters a Class name identical to the component name. You can change the class name to something more descriptive. Although the component name and class name can be the same, the component name cannot match the name of any M- or MEX-files added to the project later.

The Project version default value is 1.0. See Versions for additional information about Project version.

Project directory specifies where any project and build files are written when compiling and packaging your models. The project directory is automatically generated from the name of your current directory and the component name.

Note    You can accept the automatically generated project directory path or choose another of your liking. Once you click OK on this menu, this path is saved. If you later decide to move the project or change anything on its path, you need to redo the entire project specification process, including adding files to the project (see Project Settings) and respecifying the project directory path.

You can choose to generate C or C++ code. Components written in C give better performance, while C++ components are more readable, allowing easier modification of the generated code if needed. The files generated pertaining to the COM interface are always C++ files regardless of which option you choose.

If your models contain MATLAB Handle Graphics^® calls, include the MATLAB C/C++ Graphics library in your project by selecting Use Handle Graphics library.

You can also create a debug version of your compiled models and can specify verbose output when you invoke the MATLAB Compiler. A debug version of your component:

• Enables backtraces so that any reported error shows the M-file and line where the error occurred. The full backtrace is reported. Without debugging you get the error without any indication of where it came from in your MATLAB code.
• Allows full debugging using the Visual Studio debugger.

Once you accept these settings on the New Project Settings dialog box by clicking OK, they become part of your project workspace and are saved to the project file along with the names of any M- or MEX- files you subsequently add to the project. A project file of the name <component_name>.mxl is automatically saved to the project directory.
