Matlab Simulink Examples
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...
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...
The colon, :, is one of MATLAB’s most important operators. It occurs in several different forms. The expression 1:10 is a row vector containing the integers from 1 to 10 1 2 3 4...
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)...
What Is Image Data? The basic MATLAB data structure is the array, an ordered set of real or complex elements. An array is naturally suited to the representation of images, real-valued, ordered sets of...
Wind Mapping Data The MATLAB vector data set called wind represents air currents over North America. This example uses a combination of techniques: Stream lines to trace the wind velocity Slice planes to show...
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...
