Using the C++ Math Library

Renaming Functions to Avoid a Name Conflict

Casting arguments cannot resolve all the naming conflicts between the two libraries. For example, the MATLAB C++ Math Library functions char and double conflict with C++ data types. The library's clock() function doesn't take any arguments and thus can't be overloaded. Whenever a MATLAB function name conflicts with a C++ keyword, type, or built-in function, the MATLAB C++ Math Library appends _func to its name.

This table lists the functions in the library that have been renamed.

not	not_func
or	or_func
pascal	pascal_func (PC only)
quad	quad_func
std	std_func
struct	struct_func
union	union_func
xor	xor_func
