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)
