Processing data from loop
显示 更早的评论
Hello I have a problem, I have a video which I cut into many frames I apply on them segmentation and I get x and y values from them. So now I have triple loop cycle, and every single round it gives me x and y for one frame --> but I would like to make table or something where I can store data, for every single frame.
Now If I do it I get so many tables or I get one with data only from the last frame --> but I would like to have one table and in it has values from every frames.
How can I do that. Is there any function?
Thank you so much.

% empty table with two variables, X and Y:
t = table([],[],'VariableNames',{'X' 'Y'})
Nframes = 3;
% for each frame ...
for ii = 1:Nframes
% ... append a row to the table, containing the X and Y for this frame
% (using random numbers here):
t(end+1,:) = {rand() rand()}
end
