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, real-valued, ordered sets of color or intensity data. (An array is suited for complex-valued images.) Read More

Stream Line Plots of Vector Data

Wind Mapping Data

The MATLAB vector data set called wind represents air currents over North America. This example uses a combination of techniques: Read More

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 you to specify a twist angle (in radians) for each vertex in the stream ribbons. Read More

Displaying Graphics Images

Image Types and Display Methods

To display a graphics file image, use either image or imagesc. For example, assuming RGB is an image, Read More

plot

plot Linear plot.
plot(X,Y) plots vector Y versus vector X. If X or Y is a matrix,
then the vector is plotted versus the rows or columns of the matrix,
whichever line up. If X is a scalar and Y is a vector, length(Y)
disconnected points are plotted. Read More

edit

edit Edit M-file.
edit FUN opens the file FUN.M in a text editor.  FUN must be the
name of an m-file or a MATLABPATH relative partial pathname (see
PARTIALPATH). Read More
