That would depend on what it is exactly what you mean with mean intensity gradient. It sounds like you need to calculate the gradient with respect to some direction, and then calculate a mean. Should the output be an image, a vector, or a value? First understanding your method before you start coding is very important.

Here's my guess
% a uint8 grayscale image
inpict = imread('https://www.mathworks.com/matlabcentral/answers/uploaded_files/111239/Toner_spikkelpatroon.jpg');
inpict = rgb2gray(inpict);
% gradient magnitude (in uint8-scale)
Gmag = imgradient(inpict);
% mean gradient magnitude
meanGmag = mean(Gmag,'all')
% distribution
histogram(Gmag)
