Hi,
I have one 1x2048 array with repeated values:
A = [0 0 0 255 255 255 0 0 0 0 0 255 255 255 255 255 0 0 0 0]
and I would like to group similar element so that the output would be this:
B = [0 255 0 255 0]
I need to retain the altenation of the values because at the end of this I need to count how many 255 and 0 are there.
Any help would be much apreciated
Thanks

If you get the RunLength utility from the File Exchange, it will give you the output vector you want and the counts, in one function call.
>> [B N] = RunLength(A)
B =
0 255 0 255 0
N =
3 3 5 5 4
