Yes, you could use imhist(), but remember you need to break the image up into MxM blocks, and imhist() is a more expensive calculation than hist() or histc() is.

"where histo(i) is the value of the histogram with the intensity i"
so you need to be concerned with the output that reflects histogram values, not histogram intensities.
I think that "H = arg i max(histo(i))" is intended to mean that H is the "i" such that histo(i) is the maximum -- that is, the index of the maximum intensity.
And you still need to think more about what bin centers or edges you are going to pass in to the histogram routine you choose.
