I have a matrix where in the fourth column there will be numbers of 0 to 23. I need a separate matrix where there will be the total numbers of 0s, 1s,2s ..23s etc. Say there will be 1000 0s, 3000 1s 24000 11s etc.

histcounts()
specifically for your problem:
histcounts(x(:,4), (-1:max(x(:,4)))+0.5)

accumarray() together with findgroups(). Or use groupcounts()
I will not post code as I have a suspicion this is homework.
