Sensor fusion algorithm to determine roll and pitch in 6-DOF IMUs

Fixed point math library in C with 3d vectors and quaternions - formal verification is in process...

Simple C library for OpenGL math aimed at readability

Single header C vector/matrix/quaternion library

A simple, header only math library for the C Language.

A header-only, pure-C math library for 2D/3D graphics (matrix, vector, quaternion) Seeks to be close to C89/C90 compliant for portability. It's like a BLAS, but easier to use.
