chgicon.m

这个文件可以用来更改matlab生成的界面的标题栏的小山似的图标

function chgicon(h,filename)
%CHGICON changes the figure icon.
%   CHGICON(H,FILENAME) changes the icon of a figure to an image specified by
%   the string FILENAME, where H is a handle to the figure. If the file is not
%   in the current directory or in a directory in the MATLAB path,specify the
%   full pathname of the location on your system. If FILENAME is not a valid 
%   image file name, the function just removes the previous icon of the figure.
%
%  Example:
%         h = figure;         
%         chgicon(h,'newIcon.png'); % replace 'newIcon.png' with your image

% IMPORTANT NOTES:
%      REPLACING THE MATLAB GUI ICON VIOLATES THE LICENSE AGREEMENT
% OF MATLAB. DO NOT USE THIS FUNCTION COMMERCIALLY.
