MATLAB: About the Number property of figure function

Question

How to set the Number property of figure function of 2015B? Each time I set like this: figure('Position', [9 39 900 300], 'Number', 3, 'Name', 'Velocity'); It was wrong but I saw the example just did like this! Thanks1

Answer 1

'Number' is a read-only property.

You can call:

hFig = figure( 3 ); set( hFig, 'Position', [9 39 900 300], 'Name', 'Velocity');

though beware that the instruction:

figure(3)

will either create a new figure or, if a figure 3 already exists it will simply bring this existing figure into focus and then act upon that.
