Informally, the terms matrix and array are often used interchangeably. More precisely, a matrix is a two-dimensional numeric array that represents a linear transformation. The mathematical operations defined on matrices…

## 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…

## 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…

## Working with Images in MATLAB Graphics

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,…

## 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.…
