## Detailed Description

Include <glm/matrix.hpp> to use these core features.

For each of the following built-in matrix functions, there is both a single-qualifier floating point version, where all arguments and return values are single qualifier, and a double-qualifier floating version, where all arguments and return values are double qualifier. Only the single-qualifier floating point version is shown.
