That's done with discretize(). I'm sure there is example code in the help like there is for all functions.

% One simpple example using above code.
% Define the x and y coordinate range
x = linspace(-5,5,100);
y = linspace(-5,5,100);
% Create a meshgrid of the x and y coordinates
[X,Y] = meshgrid(x,y);
% Define the grating period and duty cycle
period = 10;
duty_cycle = 0.5;
% Calculate the phase of the grating
phase = exp(i*2*pi*(X./period));
% grayImage = double(imread('cameraman.tif'));
grayImage =angle(phase);
n=1:1:8
% n=2.^nn
% n = [256, 32, 16, 8, 4, 2];
for k = 1 : length(n)
numLevels = n(k);
posterizedImage = discretize(grayImage, numLevels);
figure(1); subplot(3, 3, 1);
imagesc(angle(phase));colormap(gray);axis off;axis tight;axis square; title('Original');
subplot(3, 3, k+1);
imshow(posterizedImage, []);
caption = sprintf('%d gray levels', numLevels);
title(caption);
figure(2); subplot(3, 3, 1);
plot(angle(phase(50,:)));title('Original');
subplot(3, 3, k+1);
plot(posterizedImage(50,:))
caption = sprintf('%d gray levels', numLevels);
title(caption);
end
