vmmlib - a templatized C++ vector and matrix math library
Its basic functionality includes a vector and a matrix class, with additional functionality for the often-used 3d and 4d vectors and 3x3 and 4x4 matrices. More advanced features include solvers, frustum computations and frustum culling classes, and spatial data structures. vmmlib also offers support for manipulating 3rd-order and 4th-order tensors, as well as several algorithms for tensor approximation.
Vmmlib is implemented using C++ templates, making it versatile. Being a header library, it is very easy to integrate into other (your) libraries and programs. There is no need to build and install a library, just include the headers and you’re set. The BSD license allows the usage both in open source and commercial closed source software.
vmmlib 1.7 includes several fixes and enhancements over the last release, such as:
