I have a noisy image of size 256x256. I need to impose a 11x11 window centered on the current pixel and find the maximum value within the window. This step should be repeated for all pixels in the image. Can anyone help me how to do that in MATLAB?

Use nlfilter:
nlfilter(img, [11 11], @(block) max(block(:)))
