GLM is extremely full featured compared to this. It's also very stable and portable. From GLM home page:

-------------

This library provides classes and functions designed and implemented following as strictly as possible the GLSL conventions and functionalities so that when a programmer knows GLSL, he knows GLM as well, making it really easy to use.

This project isn't limited to GLSL features. An extension system provides extended capabilities: matrix transformations, quaternions, half-based types, random number generation, procedural noise functions, etc.

GLM ensures interoperability with third party libraries, SDKs and OpenGL; replacing advantageously the deprecated matrix functions. It is a good candidate for software rendering (Raytracing / Rasterisation), image processing, physic simulations and any context that requires a simple and convenient mathematics library.

It is a platform independent library with no dependence to external libraries even OpenGL. GLM is written in C++98 but can take advantage of C++11 when available.
