This code demonstrates fast inverse square root algotithm from Quake 3. The script is not as fast as a c implementation. In fact it runs slower than y=1/sqrt(x); command. The purpose is to show bit ...

Microsoft Excel is a powerful tool for carrying out complex calculations. If you work on Excel, then you might come across performing mathematical operations almost every day. Sometimes, we face ...

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: Surface integral equations (SIEs) are widely used for modeling electromagnetic scattering problems. However, after their discretization via the boundary element method (BEM), the spectra and ...

One of various computer programming languages, C is the most basic and widely used language, likely because it gives maximum efficiency and control to programmers. The C language can be used for ...
