A GUI to Set Simulink Model Parameters
About the Simulink Model Parameters Example This example illustrates how to create a GUI that sets the parameters of a Simulink® model. In addition, the GUI can run the simulation and plot the results...
Working with 8-Bit and 16-Bit Images
8-Bit and 16-Bit Indexed Images Double-precision (64-bit) floating-point numbers are the default MATLAB representation for numeric data. However, to reduce memory requirements for working with images, you can store images as 8-bit or 16-bit...
The magic Function
Matlab MAGIC Function MATLAB actually has a built-in function that creates magic squares of almost any size. Not surprisingly, this function is named magic. B = magic(4) B = 16 2 3 13 5...
Subscripts
Subscripts Command The element in row i and column j of A is denoted by A(i,j). For example, A(4,2) is the number in the fourth row and second column. For our magic square, A(4,2)...
Displaying Curl with Stream Ribbons
What Stream Ribbons Can Show Stream ribbons illustrate direction of flow, similar to stream lines, but can also show rotation about the flow axis by twisting the ribbon-shaped flow line. The streamribbon function enables...
Matlab Using FFT
This demonstration uses the FFT function to analyze the variations in sunspot activity over the last 300 years. Sunspot activity is cyclical, reaching a maximum about every 11 years. Let’s confirm that. Here is...
