Hello everyone,
please consider the following lines of a matrix

[574,]   59   32
[575,]   59   32
[576,]   59   32
[577,]   59   32
[578,]   59   32
[579,]   59   32
[580,]   59   32
[581,]   60   32
[582,]   60   33
[583,]   60   33
[584,]   60   33
[585,]   60   33
[586,]   60   33
[587,]   60   33
[588,]   60   33
[589,]   60   33
[590,]   60   33
[591,]   61   33
[592,]   61   33
[593,]   61   33
[594,]   61   33
[595,]   61   33
[596,]   61   33
[597,]   61   33
[598,]   61   33
[599,]   61   33
[600,]   61   33
[601,]   62   34

Is it possible somehow to count the similarities between the first and second 
column and put them on a third column like this?

59 32 3
60 33 5
62 34 1

where (3,5,1 are the frequencies for (59,32), (60,33) and (62,34)

Best Regards
Alex
