11 Lay Out a Programmatic GUI
The Style property, pushbutton, specifies the user interface control as a push
button. Because
pushbutton is the default style, you can omit the 'Style'
property from the statement.
The
String property labels the push button as Button 1. The push button
allows only a single line of text. If you specify more than o ne line, only the
first line is shown. If you specify a component width that is too small to
accommodate the s pe cified
String, MATLAB software truncates the string
with an ellipsis.
The Positi
on
property specifies the location and size of the push button. In
this examp
le, the push bu tton is 60 p ix els wide and 40 high . It is positioned
50 pixels
from the left of the figure and 20 pixels from the bottom. This

CData property an m-by-n-by-3 array of RGB values that defines

img defines 16-by-64 truecolor
image us
ing random values between 0 and 1 (generated by
rand).
img(:,:,1) = rand(16,64);
img(:,:,2) = rand(16,64);
