Hello friends! In this tutorial, we will find the roots of a quadratic equation in MATLAB, calculate its minimum over a specified interval and display the results on a graph. This is a useful beginner project because it connects algebra, functions, input validation and plotting in one small program. The original project allowed you to choose roots, a minimum or both. We will keep that idea, but make the calculations more reliable. In particular, we will distinguish a function's roots from its minimum, account for interval boundaries and handle inputs that turn out to be linear or constant. You do not need Symbolic Math Toolbox for the numerical program below. We will use ordinary MATLAB arrays, roots , polyval and a little calculus. Figure: MATLAB is used to calculate the polynomial roots ...
Hello friends! In this tutorial, we will learn how to share a Simulink design without distributing its editable implementation. You may have developed a controller, a signal-processing algorithm or a plant model that another person needs to simulate. The challenge is to give that person a usable component while keeping your original design private. The original version of this tutorial used a generated S-function. We will keep that method, explain what it actually protects and then look at the protected-model workflow available in current Simulink releases. These approaches produce different deliverables, so the right choice depends on what the recipient needs to do. If you are distributing MATLAB functions rather than Simulink models, see our tutorial on converting MATLAB M-files to P-fil ...
Hello friends, I hope you are doing well. Today we will convert a MATLAB M-file into a P-file so another MATLAB user can run our function without receiving its readable implementation. We will start with one small calculation, create its P-code version, and then organize a distribution folder that includes everything needed to use it. The basic command is short, but a reliable delivery requires a few additional decisions. Where will MATLAB write the output? Which copy of the function will run? Does the recipient have a compatible MATLAB release and the required toolboxes? We will answer these questions as we work through the example. Figure: An example of readable M-file source; use the tutorial's pcode commands for conversion. What Are M-Files and P-Files? An M-file is a readable MATLAB p ...
