LISTING 6.25: The class interface for 4 × 4 matrices.

The constructors are for the specific size four. The constructor and assignment

operator for the base class are provided to allow implicit conversions. Static

functions are implemented to return the zero matrix and the identity matrix.

We use functions to avoid the standard template dilemma of declaring static

members that might be instantiated in multiple modules.

Geometric operations are implemented outside the class; see Listing 6.26.
