Use histogram() or histcounts() . Or accumarray()

could you give me an exemple because i'm bigginer in matlab

[Guillaume]

Aren't the examples in the documentation that Walter linked good enough?

If they're not good enough, what is it you're not understanding?

[Walter Roberson]

YourImage = imread('autumn.tif');
HSV = rgb2hsv(YourImage);
H = HSV(:,:,1);
histogram(H, 10);
