How to replace MATLAB icon from a figure window?

How to replace or delete the MATLAB icon (the peaks) from a figure window?

[Bruno Luong]

Replacing or altering figure icons violates Matlab license agreement.

Answer 1

[Paulo Silva]

replace FIGUREHANDLE with your figure handle, test with gcf
replace PATH with the path, name and extension of the icon for example
C:\Program Files (x86)\MATLAB\R2008b\toolbox\systemtest\systemtest\icons\StopElement.gif

warning('off','MATLAB:HandleGraphics:ObsoletedProperty:JavaFrame');
jframe=get(FIGUREHANDLE,'javaframe');
jIcon=javax.swing.ImageIcon('PATH');
jframe.setFigureIcon(jIcon);

Answer 2

As Bruno says, that would be a breach of the MathWorks license agreement. Specific details here:

Is it possible to control the appearance of the title bar and the title bar icon of figure windows in MATLAB?

[Jan]

Why is this icon so important for MathWorks? Does this concerns Java windows opened from Matlab also? And if I maximize a figure such that the just the innerposition fill the complete screen and the titlebar is not visible anymore?

[Siddharth Shankar]

Jan, I can't interpret the license agreement in more detail than what is outlined in that solution. If a request is made to MathWorks technical support with those questions, I am sure they will be able to provide some answers (likely after consulting the MathWorks legal team).

Siddarth, thanks for pointing out the reference to license agreement

[Vieniava]

Jan Simon, thanks. I think this is too rigid, especially when someone has got commercial license for Matlab/Compiler and sells own software.

This answer is pretty old and I've bumped into it a few times, so for the sake of new users,

here's how its done. (BTW, I'm assuming a UI figure).

fig = uifigure("WindowStyle","alwaysontop");
fig.Position = [500 500 1000 445];
pathToMLAPP = fileparts(mfilename('fullpath'));
fig.Icon = fullfile(pathToMLAPP, 'my_icon.png');
