Waitbar导致许多数字打开 - MATLAB

Question

所以,我创建了一个MATLAB脚本,需要几分钟才能执行.我决定在这里添加一个与文档相对应的等待栏:http://www.mathworks.se/help/matlab/ref/waitbar.html

我把它定义如下:

function crazyfunction4you();

h = waitbar(0,'Setting up...')

for i =1:N
    waitbar(i/N,'Loading...')
 %Some calculations is going on here

end

close(h);

end

不知何故,这是打开一个数字的数字最终崩溃我的机器.我发现这种奇怪,因为我希望只出现一个数字:

我有兴趣听到你们有类似经历的天气吗？

您需要将句柄包含在等待栏中,否则Matlab会解释您要创建另一个句柄:

h = waitbar(0,'Setting up...')
for i =1:N
    waitbar(i/N,h,'Loading...') %// Only this line changed. Added a handle
                                %// to refer to previously created waitbar
    %Some calculations is going on here
end
close(h);
