How to change scale of y-axes of an image displayed with imagesc?

9 views (last 30 days)
Hi everyone,
I have spent a lot of time trying to change the scale of the y-axes of the image shown below from 0-200 (pixels) to 0-45 (mm). Can any of you help me figure this out? To display the image, I am using imagesc.
Thank you so much for your help!

imagesc() supports the specification of the x and y ranges. I don't know what your x range should be, but since this example image is square, I'm using the same for both x and y.
inpict = imread('cameraman.tif');
imagesc([0 45],[0 45],inpict)
