hist problem

I have the following code:

    out=I(outPixel);
    [counts,values] =  hist(transpose(out),unique(out)); 
    Frequency=[counts,values];

where out=

    25
    25
    25

outPixel =

           9
         980
        1174

counts

counts =

Columns 1 through 16

     0     0     0     0     0     0     0     0     0     0     0     0     3     0     0     0

Columns 17 through 25

     0     0     0     0     0     0     0     0     0

values =

Columns 1 through 15

    13    14    15    16    17    18    19    20    21    22    23    24    25    26    27

Columns 16 through 25

    28    29    30    31    32    33    34    35    36    37

why so many values in counts and values? what's wrong with me? and Frequency have 101 values I dont know? I need unique value frequency in out. can any body help?

unique(out) gives 25, that means you ask for 25 bins, you can see it because you get counts and values with 25 elements.

do it like this:

[counts,values] =  hist(transpose(out),numel(unique(out)));

this time it is working. But Im unable to assign [counts,values] values in another matrix 'Frequency'

Its ok no problem.thanks
