Enhancing Chord and Sankey Diagrams with Interactive Data Labeling in MATLAB

Please respect the original workFor reprints, please indicate the link to this articleand the author: slandarer Although the previous chord and Sankey diagrams had scales, they sometimes did not stand out enough, so I added a data labeling feature: it is important to note that this feature requires at least R2019b version. First, I will … Read more

How to Install MATLAB R2025a on Ubuntu 25.04?

Although MathWorks officially only lists support for Ubuntu 24.04 LTS, 22.04 LTS, and earlier versions in the system requirements for R2025a (not mentioning Ubuntu 25.04). However, in a practical environment, I successfully completed the installation and running tests of MATLAB R2025a on Ubuntu 25.04 without encountering compatibility or dependency issues, indicating that this version is … Read more

PID Control Principles, Case Analysis, and MATLAB Implementation

1. Introduction to PID Control The PID (Proportional-Integral-Derivative) controller is the most classic feedback control algorithm in industrial control. It generates the control quantity through a linear combination of the proportional (Proportional), integral (Integral), and derivative (Derivative) parts of the error signal, achieving precise control of the system. Mathematical Model of PID Controller: 2. Case … Read more
