Explain the "B = b(i, j )" comment. Which little b is the big B equal to? There are 4 little b's: bBar, bRed, bGreen, and bBlue. Which one are you calling capital B? And why?

If you have your RGB image in a MxNx3 matrix, you can use
I = im2double(imread('peppers.png')); % sample image
% make sure I is double
Ibar = mean(I, 3);

Better late than never:
I was trying to find band mean values, which I initially thought you wanted. Regardless this is how I did it.
For a hypercube, Z with dimensions rowXcolXband, this would be:
band_means = sum(sum(Z,2),1)/(row*col)
