Push Button Callbacks

Each of the push buttons creates a different type of plot using the data specified

by the current selection in the popup menu. Their callbacks get data from the

handles structure and then plot it.

Surf push button callback:

function varargout = surf_pushbutton_Callback(h,eventdata,handles,varargin)

z = handles.data; % Load data from handles structure

surf(z);

Mesh push button callback:

function varargout = mesh_pushbutton_Callback(h,eventdata,handles,varargin)

z = handles.data; % Load data from handles structure

mesh(z)

Contour push button callback:

function varargout =

contour_pushbutton_Callback(h,eventdata,handles,varargin)

z = handles.data; % Load data from handles structure

contour(z)

Example – Testing the GUI

After writing the callbacks, you can activate the GUI to test it. Activate the

GUI by selecting

Activate Figure from the Tools menu or use the activator

button from the GUIDE toolbar. Select

membrane in the popup menu and press

the

Contour push button. The GUI should look like this:

1 2 ... 22 23 24 25 26 27 28 29 30 31 32 ... 179 180
