When I tackle a Wordle puzzle, I like to make all the key decisions myself. My three assistants set up puzzles and suggest words when I ask for help, but I guide the actual solution. My assistants also make it possible for me to play Wordle anywhere, anytime, even when my laptop is in airplane mode. I don't need the New York Times or access to the Web.... 더 읽어보기 >>

I am late joining the Wordle craze. Over a year ago, MATLAB programs for solving Wordle puzzles were described by Adam Filion as a guest blogger on Loren's blog and by Matt Tearle with a YouTube video. But my programs for Wordle Assistants are different. WordBot doesn't try to solve any puzzles and Words just supplies lists of possible words. I enjoy providing the solution logic myself.... 더 읽어보기 >>

R2_D2 is is the name I've given a new MATLAB program that provides animations of 2-by-2 rotation and dilation matrices. I admit I chose "dilations" so the acronym would be memorable, but otherwise the code has little to do with the famous Star Wars droid.... 더 읽어보기 >>

The 4-by-4 matrices in the panels on the following screenshots are at the heart of computer graphics. They describe objects moving in three-dimensional space and are essential to MATLAB's Handle Graphics, to CAD (Computer Added Design) packages, to CGI (Computer Graphics Imagery) in films, and to most popular video games.... 더 읽어보기 >>

I have made a half dozen blog posts about Rubik's Cube so far this year. And, during the MATLAB Central Mini Hack in October, I resurrected an old code about the Color Cube. Now, a combination of the two, Rubik/Color Qube, creates an elegant tool for investigating Matrices in Action.... 더 읽어보기 >>
