As described in the title, after upgrading to R2024b, I found that each ePWM block will automatically generate a sentence like this: uint16_T tbprdValue?Outputs = EPwm?Regs.TBPRD; where ? represents the ePWM number. However, I found that this variable is not used in any file of the project. Thou...

Yes, some readers might now argue that I used roughness in a crazy way in my last post, in my approach to finding a large twin prime pair. That is, I deliberately constructed a family of integers...

How can we use roughness in an effective context to identify large primes? I can quickly think of quite a few examples where we might do so. Again, remember I will be looking for primes with not just...

Econometric modeling is essential for analyzing economic data, making forecasts, and informing policy decisions, however, traditional approaches often require extensive coding expertise, making them inaccessible to many economists and analysts. With the Econometric Modeler app in MATLAB, you can bui...

Generative AI has become one of the most influential trends of recent years, powering tools like ChatGPT and Copilot that have transformed how we live and work. Beyond these domains, generative AI is also reshaping industries, and robotics is no exception. At MathWorks, we are excited to explore how...

In the world of Analog/Mixed-Signal Integrated Circuit (IC) design, transfer functions have long been the go-to method for representing and analyzing linear time-invariant (LTI) circuits. However, this traditional approach comes with its own set of limitations: Single-Input-Single-Output (SISO) Lim...
