how to define interval and get frequency ?

hi I have a matrix for ex: [3 5 6;5 7 9;8 3 8;6 5 3]. I want to define six interval with the weight of 1 (9-3=6/6) to have :(3,4) (4,5) (5,6) (6,7) (7,8) (8,9) (how to add up like this ?) and then find the frequency of numbers in intervals. for example it gives me in interval (3 4) frequency is 3. the actual matrix is much bigger thou. Thanks every one!

See histogram(). If you are using an older release you might need hist() or histc()

I was trying to use hist but it did not give me any histogram chart. also I need to see frequency and put them on a table. I dont know how to do that with hist(). would you please give some more details?

A = [3 5 6;5 7 9;8 3 8;6 5 3];
hist(A(:), 6)
