hello, i have images being generated after every loop and i want to store them all in one folder only. but with the saveas option, the images get overrriden to those already in the folder. do you guys know how i can fix this? thank you. i am using the following code right now:
h = findobj('type','figure');
n = length(h);
for k=1:n
saveas(figure(k),fullfile('C:\Users\Desktop\project\A data\SegmentedCharWithBlanks',['figure' num2str(k) '.jpg']));

Use sprintf() to create the filename. It can be unique for each iteration of your loop. Then use imwrite() if you want to save images. For example:
baseFileName = sprintf('Image #%d.png', k);
fullFileName = fullfile(folder, baseFileName);
imwrite(yourImage, fullFileName);
Use saveas() or save() (instead of imwrite) if you want to save figures - basically screenshots of the axes with tickmarks, labels, title, legends, stuff in the graphical overlay above the image like lines and text, etc.

I wish to write a binary image imbin to a folder with the name shown below.
WriteFileName = "C:\ISI-Kappa\FromWorkBin\Front_1\b_180311788230057_Front.jpg"
My command is imwrite(imbin, WriteFileName)
I get this error: Error using imwrite>parse_inputs (line 523)
A filename must be supplied.
I appreciate any help to resolve this error

Are you sure that folder already exists because I'm not sure imwrite() will create folders automatically, though it might. You also might try using forward slashes. What does this say:
whos imbin
Is it a uint8 image?
