| Using the C++ Math Library | |
This chapter describes how to write print handlers, handle exceptions, and replace default memory management.
Defining a Print Handler
The MATLAB C++ Math Library is designed to run on character-based terminals and in graphical, windowed environments. Simply using printf() or a similar routine is fine for character-terminal output but insufficient for output in a graphical environment. To support programs with graphical user interfaces, the library allows you to specify how it displays output.
The MATLAB C++ Math Library performs some output, in particular it displays error messages and warnings, but doesn't perform input. The MATLAB C++ Math Library's output requirements are very simple. The library formats its output into a character string internally and then calls a function, the print handler, that prints the string. If you want to change where or how the library's output appears, you must provide an alternate print handler.
