Matlab Image Types
Indexed Images
An indexed image consists of a data matrix, X, and a colormap matrix, map. map is an m-by-3 array of class double containing floating-point values in the range [0, 1]. Each row of map specifies the red, green, and blue components of a single color. An indexed image uses “direct mapping” of pixel values to colormap values. The color of each image pixel is determined by using the corresponding value of X as an index into map. Values of X therefore must be integers. The value 1 points to the first row in map, the value 2 points to the second row, and so on. Display an indexed image with the statements Read More
Adding Text Annotations to Graphs
What Are Text Annotations?
Text annotations are boxes containing text strings that you compose. The box can have a border and a background, or be invisible. The text can be in any installed text font, and can include TeX or LaTeX markup. You can add free-form text annotations anywhere in a MATLAB figure to help explain your data or bring attention to specific points in your data sets. Read More
