Passing Parameters to Apps Built with App Designer

I need to figure out how to pass a parameter to a MATLAB App that is built with App Designer. In this case, I want to pass a parameter to a MATLAB Web app, but since making the video I have found out that there is currently no documented method to do this, so I can't show you that. However,...

Women technologists share the best – and the worst – career advice they’ve received

Headlines abound about how women are underrepresented in tech, as do recommendations to address the issue. But one of the best ways to increase the number of women pursuing STEM careers is for women in technology to network with others. In that vein, a major event is just weeks away. The Grace Hopper Celebration (GHC), the world’s largest gathering...

Experiments With Kuramoto Oscillators

I have learned a lot more about Kuramoto oscillators since I wrote my blog post three weeks ago. I am working with Indika Rajapakse at the University of Michigan and Stephen Smale at the University of California, Berkeley. They are interested in the Kuramoto model because they are studying the beating of human heart cells. At this point we have some interesting results and some unanswered questions....

Editing (Another) Function While Stopped at a Breakpoint

I find myself needing to update one of my functions that takes a while to run, in this case, to replace the contents of a large string array depending on certain criteria. I want to have the data available to operate on, so I will stop at a breakpoint. Features covered in this code-along style video include: Debugging, Code...

Curling Game Update: App Designer and Stateflow

Someone recently challenged me to convert the curling simulator we published a few years ago (See this post and this post) to take advantage of new features not available at that time: App Designer and Stateflow for MATLAB. As you can guess, this is not the kind of challenge I can say no to! You can find the final result...

MATLAB wins Hackathon

This post is from Paola Jaramillo, Application Engineer from the Benelux office. Back in February, I attended a hackathon hosted by Itility: meeting for 3 hours to solve an image classification problem while also enjoying pasta and networking with peers. I was there primarily to learn and see how other engineers and researchers were using machine learning in...

Using reshape to rearrange image color components

I recently saw some code that transformed the RGB pixel values of an image into a Px3 matrix, such that each row contained the red, green, and blue color components of a single pixel. Today I want to show that code fragment, explain it, and then demonstrate what I think is the fastest possible to perform that transformation in MATLAB.I...

Mind-controlled robot that works without brain implants

Mind-controlled robots have long been featured in science fiction, but thanks to new research in brain-computer interfaces (BCIs), they are no longer fiction. BCIs are enabling thought-controlled external devices. BCIs are communication pathways between the brain and an external device that translate a person’s brain activity into a signal that controls the external device, such as a robot. A...

Kuramoto Model of Synchronized Oscillators

Fireflies on a summer evening, pacemaker cells, neurons in the brain, a flock of starlings in flight, pendulum clocks mounted on a common wall, bizarre chemical reactions, alternating currents in a power grid, oscillations in SQUIDs (superconducting quantum interference devices). These are all examples of synchronized oscillators.The Kuramoto model is a nonlinear dynamic system of coupled oscillators that initially have random natural frequencies and phases. If the coupling is strong enough, the system will evolve to one with all oscillators in phase....

Estimating pi Using Buffons Method

I recently attended the ICIAM meeting in Valencia, Spain which meant I got to hang out with my pals Carlos Sanchis and Lucas Garcia :-)! Carlos showed me a problem he was working with Professor Fernando Gimnez from UPV regarding an app for estimating $\pi$ using Buffon's method. Here's the problem statement from Wikipedia:Suppose we have a floor made of parallel strips of wood, each the same width, and we drop a needle onto the floor. What is the probability that the needle will lie across a line between two strips?Interesting that the original intention had nothing to do with computing $\pi$ ! There's some fun, powerful, yet fairly easy code to demonstrate the algorithm....

The QR Algorithm Computes Eigenvalues and Singular Values

The QR algorithm is one of the world's most successful algorithms. We can use animated gifs to illustrate three variants of the algorithm, one for computing the eigenvalues of a nonsymmetric matrix, one for a symmetric matrix, and one for the singular values of a rectangular matrix. In all three cases, the QR iteration itself is preceded by a...
