A discussion of this technology’s promise, as well as pitfalls and perils — Science work, whether taking place at the bench, screen, class room or conference room, can all benefit from artificial intelligence. It is already making an impact on how we cite papers,¹ with examples like SemanticScholar. For writing there are AI-powered assistants like Grammarly, and tools like Github Copilot for coding…

I’ll demonstrate how simply changing the precision of your numeric data can cut your memory usage by half or even more Have you ever ran into an issue with memory in MATLAB and you went looking online?

Academic scientists steeped in MATLAB will need to be comfortable with classes to successfully transition to Python When is the last time you sat down to your MATLAB console and typed out something like mydata.myfunction()? Right now you might be saying “That’s not MATLAB”. …

Tables are very versatile which means there isn’t a single document explaining the uses you might have for them, which is why I created this tutorial. In this tutorial, I will outline best practices for making a table, filtering a table, and displaying table contents. In MATLAB, nearly every entry point for a thorough exploratory data analysis or machine learning application is a table. Sure, you can do these…

If you are using MATLAB to analyze data containing two or more normally distributed populations, this tutorial could help you sort them out Let’s begin by creating a hypothetical dataset containing data from three random distributions. rng(5) % Initialize the random number generator mu = [5,10,15]; % Choose mean and…

One of the most desired plot types, a favorite of R users, is the violin or half-violin. In this post I show how to accomplish this in MATLAB using two built-in functions: ksdensity and patch. — Has this ever happened to you? You have some great data for a boxplot, but you also want to view the distributions. Your supervisor suggests something called a violin, but you’re a MATLAB native and the last time you saw a violin was in your high school orchestra section. So you go looking:

This article describes how Selenium in Python can be used to easily obtain pre- and post-market quotes These days, keeping track of pre- and post-market prices can mean the difference between an appreciable gain and a fantastic one. For example, when AMD announced their earnings on February 1st, the post-market…

For most scientists, there is a ton of utility in switching between colormaps. Here I describe a less commonly-used method to get even more from your colormap. If you’re like me and you learn by reading code, feel free to skip to the end for a code snippet from MATLAB. When would you want to do this? …

Joining tables is an art and the benefits and consequences of joining are not always be clear. Here, I’ll describe a simple case that works well even for a beginner learning to use tables. Joining for enhanced boxplots Here, I’ll use the generic join to spruce up a boxplot and accentuate a pattern in…
