Hi,
Sorry if this has been asked / answered many times or very simple etc. etc!
If I have a cell array say Array = {B C A;1 3 2; D E F}
Is it possible to sort the first row in order, so its A B C, with the second and third rows changing corresponding to to this initial sort?
Final answer being {A B C;2 1 3;F D E}
Thanks in advance Matthew

Array = {'B' 'C' 'A';1 3 2; 'D' 'E' 'F'}
out = sortrows(Array',1)';
OR
[id id] = sort(Array(1,:))
out = Array(:,id)

What is the syntax for sorting cell arrays in descending order? Thank You!

sortrows(Array',1)':: here since sortrows works for columns ,(sorting elements in a column of a matrix...)
you needed the row to be sorted here , so Array' is the transpose of it and then doing a retranspose of the result by doing sortrows(Array',1)'<-- to get the original matrix
for descending its simple, just add 'descend' at the end of these arguments (Array',1,'descend')'

It is not clear to me what your cell array really looks like, as your example is not valid, but the SORTROWS command should work.

Sorry if not clear...
The array consists of both strings and numbers
so Array = {'B' 'C' 'A';1 3 2;'D' 'E' 'F'}
where the letters are strings and the numbers numbers!
i tried the sortrows and it did not work
Thanks again, matthew
