save images inside for loop

In the below for loop, i runs from 1 3 5 7 ....100. But I would like to save images Y1.bmp, Y2.bmp, Y3. bmp .... instead of Y1.bmp, Y3.bmp, Y5. bmp. Is there any way to implement this in the below for loop

for i = 1:2:100
    %% operation %%
saveas(gcf,sprintf('Y_%d.bmp',i))
end

Hi @MechenG,

You can achieve this by using an additional counter that tracks the number of images saved.

Here’s a modified version of your loop:

imageCounter = 1; % Initialize a counter for saved images
for i = 1:2:100
    %% operation %%
    saveas(gcf, sprintf('Y_%d.bmp', imageCounter));
    imageCounter = imageCounter + 1; % Increment the counter
end

This way, you'll save images as Y_1.bmp, Y_2.bmp, Y_3.bmp, and so on, regardless of the values of i.

Hope this helps!

Thank you very much!. This was exactly I am looking for it.

for i = 1:2:100
    %% operation %%
    saveas(gcf,sprintf('Y_%d.bmp',(i+1)/2))
end
