different file name in saving images

In the below script, based on iteration numbers in for loop, I need to change Y_10, Y_20,Y_30,Y_40.....Y_100

Is there a way to achive this instead of renaming everytime ??

saveas(gcf, sprintf('Y_10mm'), 'bmp')
savefig(gcf, sprintf('Y_10mm')

In whatever loop you're using, create the filename something like this:

k = 10 % whatever number you need

k = 10

sprintf('Y_%03dmm.bmp',k)

ans = 'Y_010mm.bmp'

Unless you have a need to avoid it, zero-pad your numbers so that your files sort correctly and are easier to read back in corresponding order

Hi,

Incase, if have something like this Y_10mm_X_20mm, here basically I need to change both X and Y values

Any suggestions please ??

saveas(gcf, sprintf('Y_10mm_X_20mm'), 'bmp')

You can add more something like so.

h = 10; % for example
w = 20;
sprintf('Y_%03dmm_x_%03dmm.bmp',h,w)

ans = 'Y_010mm_x_020mm.bmp'

how about repeat in for loop for many series number of figure

for h = [10 20 30]
    for w = [20 21 22]
        filename = sprintf('Y_%03dmm_x_%03dmm.bmp',h,w);
        %some calculation
        imwrite(YourImage, filename);
    end
end
