4 The Design and Call of COM Modules
4.1 M-File Algorithm Programming
The algorithm function file is programmed in the MATLAB M-file editor with one
input parameter and saved as jc.m file.

4.2 The Creation of COM Modules
COM Builder is a COM builder provided by MATLAB software which can transfer
M-file algorithms into independent COM modules [3]. Objects built can be used un-
der any developing environment which supports COM objects. A COM module could
involve many classes and each class can include many M files. Class files will be
after compiling of M files.
