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 method is developed for constructing an approximate plot of a function of three independent variables. The plot is similar to a conventional contour map except that there are three scales to ...

Abstract: A MATLAB code capable of plotting ambiguity functions of many different radar signals is presented. The program makes use of MATLAB's sparse matrix operations, and avoids loops. The program ...

Abstract: This paper introduces a generic dynamic programming function for Matlab. This function solves discrete-time optimal-control problems using Bellman's dynamic programming algorithm. The ...

Talk of “gain-of-function” research, a muddy category at best, brings up deep questions about how scientists should study viruses and other pathogens. By Carl Zimmer and James Gorman At a Senate ...

Learn how to make everything from basic line graphs to racing bar charts — all interactive and easily animated — with the echarts4r R package. While I’m mostly settled on ggplot2 for static plots, I’m ...
