• How It Is Organized

Part III, "Global Function Reference," summarizes the global functions of the Essential Math Module. Many of the global functions are overloaded; that is, they take one of several different Essential Math Module objects as arguments. Many of the standard C functions, such as cos() or exp(), are overloaded to operate element-by-element on vectors and matrices. Some functions are templatized.

The functions are presented in alphabetical order. Each function entry contains:

• The name of the entry

• A table that contains:

• The function Prototypes, which consist of the return types, the function names, and the argument type or types

• The function Header File(s)

• A Description of the function, sometimes followed by an Example Program. Note that the subscripts in the function descriptions indicate "an element of." For example, v_i means "element i of v."
