【原创】GUI启动画面制作的另一途径
通过matlab的java接口实现的。使用方法跟调用matlab的内建函数一样。在用GUIDE编的GUI中使用时，在相应的openingfunction中调用该函数即可。Re:【原创】GUI启动画面制作的另一途径
贴出来：function splash(filename,varargin)
%SPLASH(FILENAME,FMT,TIME) creats a splash screen using image from the
% file specified by the string FILENAME, where the string FMT specifies
% the format of the file, and TIME is the duration time of the splash
% screen in second. 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 SPLASH cannot find a file named FILENAME, it looks
% for a file named FILENAME.FMT.

% Note
% Java requires uint8 data to create an instance of the Java image class,
% java.awt.Image. If the input image is of class uint8, jimage contains
% the same uint8 data. If the input image is of class double or uint16,
% im2java makes an equivalent image of class uint8, rescaling or offsetting
% the data as necessary, and then converts this uint8 representation to an
% instance of the Java image class, java.awt.Image.
