Counting number of unique elements in a matrix

I have a matrix, 2xT. It contains value PAIRS that are unique and some that are repeated.

I would like to order the matrix by the pairs that occur the most frequently.

myData = randi([0 20], [10000 2]); %make up some data
[C,ia,ic] = unique(myData,'rows');

such that %isequal(C(ic,:), myData) =1. Great.

I now try and work out the ordering

[nOccurances IX] = sort(histc(ic, 1:length(ic)), 'descend');

This gives nOccurances which looks sensible.

Now I try and output:

myDataSorted = myData(ic(IX),:);

The output value is just wrong.

Where have I gone wrong? Thank you!!

SOLVED:

myData = randi([0 20], [10000 2]); %make up some data
[C,ia,ic] = unique(myData,'rows');
[nOccurances IX] = sort(histc(ic, 1:length(ic)), 'descend');
idY = (nOccurances==0);
nOccurances(idY) = [];
IX(idY) = [];
myDataSorted = [nOccurances C(IX,:)];
