Image processing helps solve the age-old mystery of “Why do zebras have stripes?”

Why are zebras striped? The hypotheses are many and varied. Do the stripes work as camouflage, temperature regulation, or a barcode so that individuals are distinguishable in a herd? The most popular theory by far, dating all the way back to the 1870s and Charles Darwin’s theory of natural selection, was that the zebra stripes acted as a form of...

Matrix Eigenvalue Dating Service

This is a summary of my talk at the conference Celebrating the Centenary of James H. Wilkinson's Birth at the University of Manchester, May 29.Jim Wilkinson knew that a matrix with badly conditioned simple eigenvalues must be close to a matrix with multiple eigenvalues. How can you find the nearest matrix where some of the eigenvalues have found their mates?Much...

My Web Scraping App: Only Get HTML Content if Page List Changes

Currently, my web scraping app reads the HTML content of the list of pages, then searches for pattern matches. I want to change it, so that it only reads the HTML content if the list of pages changes. This will make it quicker for me to iterate on different patterns. Features covered in this code-along style video include: App...

You may have noticed that we have some functions that return no output if none is requested, and yet some functions always return something, even if not asked. What's a good way to achieve this in MATLAB?I do want to point out that while we used to use this programming pattern more often, we have tended to back away from...
