Using the C++ Math Library

How to Call C++ Library Functions

The following sections use the cos(), tril(), find(), and svd() functions to demonstrate how to translate a MATLAB call to a function into a C++ Math Library call. Each of the functions demonstrates a different aspect of the calling conventions, including what data type to use for C++ input and output arguments, how to handle optional arguments, and how to handle MATLAB's multiple output values in C++. Specifically, the topics covered include:

• Returning One Result and Passing Only Required Input Arguments
• Passing Optional Input Arguments
• Passing Optional Output Arguments
• Passing Optional Input and Output Arguments
• Passing Any Number of Inputs
• Passing Any Number of Outputs
• Summary of Library Calling Conventions
• Example Program: Calling Library Functions (ex2.cpp)
