When displaying an image in imshow, I get the error that "Image is too big to fit on screen; displaying at 67%" and I notice Moire patterns in the resulting image. I'd like to know how the image is downsized to display at reduced size. Is it subsampled, or something else?

Turn off the warning....
warning('off', 'Images:initSize:adjustingMag');Hi, You can use rescale() function to scale down / up your data to any given range. Refer to the code below. It scales a demo data between a given upper and lower range.
% Demo data for imagesc plot
imageData = magic(100);% Plot your image data
imagesc(imageData);% Set your preferred axis
axis([-10 37 6 56]);hold all;% Demo data for scatter plot
x1 = rand(1,500); y1 = rand(1,500);% Rescale scatter plot data to your preferred range
x1_re = rescale(x1, -10, 37);y1_re = rescale(y1, 6, 56);% Scatter plot your rescaled data
scatter(x1_re,y1_re,'magenta','filled');
Hope this helps!
