Hi,

I need to sort a n by 2 cell array along the second dimension. The first dimension contains structures and the second dimension contains a numerical value. I want to sort my structures by their corresponding numerical value, so in other words, I want to sort my array by the second dimension.

Please let me know if/how this is possible.

Thanks in advance!!
Vivek

So if I am not mistaken you have something like:
yourCell = {struct,3;struct,1};

if cellfun('prodofsize',yourCell(:,2)) == 1
[IDX,IDX] = sort(cell2mat(yourCell(:,2)));
yourCell = yourCell(IDX,:);
end

If this is confusing, try this (looking different, but does exactly the same assuming that the numbers in the 2nd column are scalars):
[dummy, IDX] = sort([yourCell{:}]);
yourCell = yourCell(IDX,:)
