GMLinear is an implementation of matrix and vector operations in pure GML. You can use it to simplify many common calculations in 2D and 3D geometry and implement algorithms/formulas involving linear algebra. Hard-coded optimized functions are available for 2D, 3D and 4D vectors and 2x2, 3x3 and 4x4 matrices.

Very well made
This is a really well made add-on. I'm surprised there is such little utilization.
