Displaying Curl with Stream Ribbons

matlabtutorials — Sun, 02 May 2010 18:37:59 +0000

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

A GUI to Set Simulink Model Parameters Example 2

matlabtutorials — Sun, 02 May 2010 16:27:47 +0000

Running the Simulation from the GUI

The GUI Simulate and store results button callback runs the model simulation and stores the results in the handles structure. Storing data in the handles structure simplifies the process of passing data to other subfunction since this structure can be passed as an argument. Read More

A GUI to Set Simulink Model Parameters

matlabtutorials — Sun, 02 May 2010 16:20:52 +0000

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 in a figure window. The following figure shows the GUI after running three simulations with different values for controller gains.

The example illustrates a number of GUI building techniques: Read More

Matlab Editing Plots

matlabtutorials — Sat, 24 Apr 2010 20:47:21 +0000

Why Edit Plots?

MATLAB graphs are formatted to provide readability, setting the scale of axes, including tick marks on the axes, and using color and line style to distinguish the plots in the graph. However, if you are creating presentation graphics, you might want to change this default formatting or add descriptive labels, titles, legends, and other annotations to help explain your data.
