I have got a sequence with size of 1 million. I want to plot a pdf for this sequence by putting same values together. Does anyone have any idea?

A=[1 1 1 1 1 1 2 2 2 2 3 3 3]
[a,b,c]=unique(A)
out=accumarray(c,A') % corresponding to a'
[a' out]

A million elements is not large at all - just a very small fraction of the number of elements in an ordinary digital image for example. It sounds like you just want the histogram. If you have all integers:
data = [1 1 1 1 1 1 2 2 2 2 3 3 3]
edges = 1 : max(data(:));
counts = histc(data, edges)
counts =
6 4 3
Though perhaps I misunderstood because you have 5,4,3 instead of 6,4,3. Can you explain how you got the 5? Did you just ignore the first element or something???
