Introduction Implementing online training of neural networks in MATLAB-Simulink typically requires combining Simulink models and MATLAB scripts. Here are the general steps: Building the Simulink Model: Use the Neural Network Toolbox in Simulink to add a neural network block. This can be done through the “Add Block” menu. Configure the structure, input, output, and other … Read more
Signal processing is one of the core technologies indispensable in fields such as electronic engineering, communication technology, and automation control. It not only relates to the acquisition, conversion, analysis, and expression of information but also directly affects the performance of systems and the effectiveness of applications. MATLAB, as a high-performance numerical computation and visualization software, … Read more
Any two points on a sphere and the center of the sphere form a great circle’s minor arc, which represents the minimum surface distance between these two points. Therefore, can we extend this to find the distance between each pair of points and calculate the sum of distances from a certain point to all other … Read more

Nested Functions MATLAB allows one or more functions to be completely nested within another function. To define a nested function, you must add the <span>end</span> statement at the end of the nested function and the main function (otherwise, they are local functions), and a good coding style is to add indentation for nested functions. Nested … Read more
