how can I display one of the images instead of displaying all? can anybody help me please

i am trying to read images from a folder and display one of them.

image_folder= 'C:\Octave\Octave-4.2.1\share\octave\packages\images' filename=dir(fullfile(image_folder,'*.jpg')); total_images=numel(filename);

for n=1:total_images f=fullfile(image_folder,filename(n).name); our_images=imread(f)

figure(n)
imshow(our_images)
end

Well you've created a for-loop, so it shows all of the images in those figures. If you only want to display 1 specific image, you should just get rid of the loop and specify wich image you want to display.

image_folder= 'C:\Octave\Octave-4.2.1\share\octave\packages\images' 
filename=dir(fullfile(image_folder,'*.jpg')); 

n = 20; % from `filename`

f=fullfile(image_folder,filename(n).name); 
my_image=imread(f);

figure();
imshow(our_images)

This is another type of question, you should probably create a new post for this.
