Given an n x n square matrix A, if there exists another matrix B such that AB = BA = I (where I is the identity matrix), then B is called the inverse matrix of A and is denoted by A-1. The general ...

Abstract: Hyperbolic tangent function is approximated using piecewise linear approximation. This approximation can be used in any embedded hardware architecture where occupied chip space is a ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

A few weeks ago, my ears perked up when a gaggle of middle school volleyball players in my car were talking about the teachers they don’t like; I have an unfortunate appetite for tweenage gossip, and ...

Q. Are there any alternatives to traditional PivotTables in Excel? A. The first thing that comes to mind is the function GROUPBY. The primary purpose of GROUPBY is to make data analysis easier by ...

Once the domain of esoteric scientific and business computing, floating point calculations are now practically everywhere. From video games to large language models and kin, it would seem that a ...

In this paper, an efficient approximate analytical technique for solving the one-dimensional Schrödinger equation (SE) with an attractive Gaussian potential is developed. This technique is based on ...
