start:1

stop:200

for i = start : stop

XX

end

But i need to continue from 101, 102,... after 100. Kindly help me identify the problem.

The easiest solution is to use my FEX submission natsortfiles. It fixes the order of an ASCII sort to take into account any numeric values in the strings. Note that it requires the file natsort to work!

It simply sorts a cell array of filenames into the order you want:

S = dir('*.jpg');

S = natsortfiles(S);

for k = 1:200 % first 200 files

F = S(k).name;

... your code

end

Note that this answer assumes that your files are sequentially numbered without any gaps. If this is not true, then you need to give more information on the filenaming logic.

Here is one way of solving your task using my answer:

P = 'E:\New Folder';

S = dir(fullfile(P,'*.tif'));

S = natsortfiles(S);

for k = 1:200

F = fullfile(P,S(k).name);

I = imread(F);

figure;

imshow(I);

end

Note:

- you will need to download NATSORTFILES.
- I changed the loop variable from i to k, because in MATLAB i is the imaginary unit.
- I used fullfile to create the path strings, which is much more robust than using strcat.
