Abstract: Computing the matrix square root and its inverse in a differentiable manner is important in a variety of computer vision tasks. Previous methods either adopt the Singular Value Decomposition ...

Abstract: This paper deals with the computation of reciprocals, square roots, inverse square roots, and some elementary functions using small tables, small multipliers, and, for some functions, a ...

This is a benchmark of the "fast inverse square root" algorithm found in Quake 3 Arena source code. I created this because a coworker "kindly suggested" I use this "very optimised function" in some ...

This module is a port from Quake 3's inverse square root algorithm. This is fastest inverse square root algorithm. It is not as accurate as the quake_inverse_sq.fined ...
