Hello,
I have a 1x3x70 cell array with text, double and a 1x100 matrix How can I sort this elements according to the second column (double)
The cell array look like this :
myCellTest{1,1,62} =
./ref/image62.gif
myCellTest{1,2,62} =
195.7271
myCellTest{1,3,62} =

Hi, in order to achieve what you need, you have to perform few steps.
% Extract numeric vector containing just the value used for sorting
unsortedDataVector = [myCellTest{1,2,:}];
% Sort it and keep the indexes
[sortedDataVector,sortIndexes] = sort(unsortedDataVector);
% Use the ordering information for whatever purpose, e.g. to create a new,
% sorted cell array:
mySortedCellTest = cell(size(myCellTest)); % preallocate
[mySortedCellTest{1,1,:}] = deal(myCellTest{1,1,sortIndexes});
[mySortedCellTest{1,2,:}] = deal(myCellTest{1,2,sortIndexes});
[mySortedCellTest{1,3,:}] = deal(myCellTest{1,3,sortIndexes});

[~,idx] = sort([myCellTest{:,2,:}];
mySortedCellTest = myCellTest(:,:,idx);
