Cell array to meet conditions and cell indexing

I apologise in advance for incase this is unclear.
I have an array, with X Y columns and another column that identifies the other X and Ys that have met a previous condition. For example A=[16x1 double 16x1 double 8; 12x1 double 12x1 double []; 15x1 double 15x1 double [13,15]..... up to 19 rows]. If the condition was not met there is no match and so the third column reads [], as given for A(2,:). If two sets of x and y coordinates have been matched, then these can be found in rows 13 and 15 for example of column 1, for A(3,:).
I want to therefore have an output of the original X and Y sets, the matching rows (I already have) and the matching X Y coordinates. I had had numerous errors since there are empty cells, which I do not want to delete. Also, the number of matches changes each time, so concatenating brings errors.
Thankyou.

Please at least give us the arrays to work with. Edit your question, click the paperclip button, then both Choose file and Attach file buttons.

I'm not really clear on the format of the output you want, but the following should give you an idea what to do:
C = {[1:10]', [21:30]', 8; [41:45]', [51:55]', [2 4]; [60:70]', [80:90]', []} %demo data
C(:, 4) = cellfun(@(x, y, row) [x(row), y(row)], C(:, 1), C(:, 2), C(:, 3), 'UniformOutput', false)
celldisp(C(:, 4))

The loop solution should have read:
rows = X_Y_Match{rowidx, 3};
Sorry about the typo.
