empty entry using ginput !!
显示 更早的评论
Hello! I am using the function ginput in order to get the coordinates from a figure but I get x and y as a 0x0 double, any possible reason for this, the code I am using to do so is really very basic!
while ~isempty(t)
[x,y]=ginput(1);
end

[x,y]=ginput(1);
works fine for me, but I don't know what you are trying to do in the while loop. t never changes so either it is empty at the start and x, y never get set or it isn't empty at the start and your loop is infinite.

You accepted this, but how does this explain why your x and y were empty? Adam said it worked fine for him and didn't produce empty x and y.

Are you sure you're not just hitting enter before left-clicking, or maybe you're right clicking instead? For me, when I left click, x and y definitely have values.
