Many years ago we ran an online MATLAB Programming Contest. It was fun! We had a contest once every six months or so from around 2000 to 2010. Fun side note: after that experience, we wanted to build a coding game that ran continuously rather than in discrete bursts. That's how Cody came about. Here's how the original contest worked. Players were given a difficult optimization problem to solve (something NP-hard like the Traveling Salesman Problem). They would submit a function that would be tested against a hidden test suite and given a score that combined the quality of the optimization (lower is better) and the speed of the calculation (lower is better). Once scored it would appear on the leaderboard with the code freely available for all to see and use. In other words, it was an open source programming contest. This had some big implications. Let's say your code was in the lead and someone modified a single line to make it go a tiny bit faster. BOOM! That person is...

Insights from a cross-industry executive panel spanning automotive engineering and semiconductor     The automotive industry’s shift to software-defined vehicles (SDVs) is often framed as a technology evolution. In practice, it is a workflow re-architecture: a change in how product value is created, integrated, validated, and continuously improved over the vehicle’s lifetime. As software content grows and compute architectures become heterogeneous, the late-in-the-cycle integration event has become the most expensive habit the industry is trying to break. Virtualization is emerging as the most pragmatic lever to do that—not because it replaces hardware, but because it stabilizes engineering throughput in a world where complexity and schedule pressure compound.   Watch the executive panel event recording and review the panelists' presentations   From tool choice to...

Every engineering organization is trying to move faster, make better decisions earlier, and align teams that come from very different engineering cultures. And in a world where software now defines, and increasingly delivers, most of a product’s differentiated value, the tension between systems engineering and software engineering has never been more visible and damaging. This raises a question I hear across industries: Is the V-diagram still relevant in a world of software-defined systems? The V-Diagram: A Useful Structure, Often Misused as a Process The V-diagram was never meant to be a timeline. It was created to clarify responsibilities and relationships, not to dictate a sequence or prescribe a process. Yet many teams interpret it as a left-to-right development flow (as shown in the figure below), which leads directly to its association with the waterfall model. And that misconception is costly. Waterfall requires complete requirements upfront, limits iteration,...

Effective risk management increasingly requires understanding how climate‑related factors can influence market valuations and balance‑sheet resilience. CRISK provides a transparent, market‑based framework for estimating the expected capital shortfall a bank might face under a climate stress scenario.

At the MathWorks Finance Conference, Michael Robbins (Columbia University) and Arpit Narain (MathWorks) discussed the CRISK framework, a practical, data‑driven approach to incorporate climate factors into systemic risk analysis.

What Is CRISK? Climate stress‑test framework linking climate science, economic outputs, transition‑risk modelling, and financial valuation to assess the...

Building something truly new often means building everything yourself. This was the reality facing Raptee.HV, an India-based startup developing the country’s first high-voltage electric motorcycle. While high-voltage architecture has become common in electric cars, it is not the standard in the two-wheeler market. There is no established ecosystem to build upon, no off-the-shelf components, no reference designs, and no proven playbook. The team did what many deep‑tech startups must do: they started from the ground up. Designing a Motorcycle From Scratch Raptee.HV’s goal is to deliver a technologically advanced motorcycle that elevates the everyday commuting experience. Pursuing a high‑voltage architecture means the team has to design and validate every major subsystem themselves. From the powertrain and battery pack to the motor controller and suspension, each component is engineered, modeled, and tested in-house. For a small team...

Toshi’s pick this week is MATLAB on the Steam Deck from Reddit by Mindless_Egg7324 A recent Reddit post showed something unexpected and fun: a user successfully installed MATLAB on a Steam Deck, and the community loved it—nearly 500 upvotes and an entire thread of enthusiastic reactions. The Steam Deck runs SteamOS, which is based on Arch Linux. While MATLAB officially supports a set of validated Linux distributions—including Ubuntu, Debian, Red Hat Enterprise Linux, and SUSE Linux Enterprise Desktop/Server—Arch Linux and SteamOS aren’t on the official support list. That makes this achievement even more...

“Isn’t digital engineering just another way of saying digital transformation?” It’s a question we hear often and one that sounds reasonable on the surface. After all, both terms are used to describe how organizations modernize, adopt new tools, and rethink the way they work. But as we’ve discovered through countless conversations with customers and colleagues, treating these concepts as interchangeable can create confusion, unrealistic expectations, and stalled progress. During a recent discussion with Jason, we unpacked where these ideas overlap and, more importantly, where they diverge. Digital Transformation: The Big Umbrella Kirsten: When people talk about digital transformation, they’re usually talking about something very broad. It’s an organizational shift that touches everything, not just engineering. That includes how people are trained, how business workflows operate, how acquisition processes work in aerospace and defense, and how marketing or sales systems...

Systemic risk modeling is essential for central banks as financial systems grow more interconnected and vulnerable to sudden shocks. From market implied indicators to climate stress testing and network analytics, MATLAB provides a unified environment for developing models that help institutions identify vulnerabilities and prepare for emerging risks.

This overview highlights how central banks—including the Bank of England and the Austrian National Bank (OeNB)—use MATLAB to build scalable, transparent, and reproducible systemic risk frameworks.

Systemic risk modeling refers to the set of quantitative methods used to assess the stability of an entire financial system—not just individual institutions. Central banks rely on these models to:

When I read data from the web, using webread or websave, usually all records returned have the same information and, as a result, appear in MATLAB as a struct array. But sometimes they do not have the same information and appear as a cell array containing structures with different fields. This has recently happened in one of my scripts, so I need to address this but I think it would be useful for me to come up with a utility to handle this scenario in general, as it often happens.
