getFile/ imread cooperation error
显示 更早的评论
Hello, so i have this little app i made, and right now im working on exceptions.
And my problem is, probably not that complicated, but i cant find solution. So to start, I let user pick a file, the jpg ( its stated in my work that database pics are all jpg blah blah ), next thing is imread. As long as user chooses the file, everything is great, but, i need an exception ( probably an if end) that would cover the Cancel option, because if user wont pick a file, imread goes crazy.
IMG = uigetfile('*.jpg');
IMG0=imread(IMG);
all im asking is, how to make an exception that would cover the Cancel option,
Thanks in advance <3

if isnumeric(IMG); return; end
better style. Otherwise you are comparing the vector of characters to 0 and relying on the fact that if IMG==0 is treated the same as if all(IMG==0)
