You can use the two outputs of imhist to obtain gray levels and count of each level. Use then the second output of max to obtain the index of the level whose count is maximum. Finally, the result is the level with that index.

[count levels] = imhist(I); %// get levels and count of each level
[~, v] = max(count); %// v is the index corresponding to maximum count
result = levels(v); %// the result is the level that has that index
