I am trying to sort the following matrix in alphabetical order and sortrows(A) seems to do the trick, except for the fact that the word "Happy" doesn't get properly sorted. Is there a way to make sortrows case insensitive, or accomplish my objective with a different function that is flexible enough to accommodate an option for case insensitivity?
Thanks in advance.
A=[Happy the man and happy he alone]

Your question is not clear, and the variable A=[Happy the man and happy he alone] does not make sens, maybe
A='Happy the man and happy he alone'
Or
A={'Happy' 'the' 'man' 'and' 'happy' 'he' 'alone'}

A={'Happy' 'the' 'man' 'and' 'happy' 'he' 'alone'}
[~,idx]=sort(upper(A))
out=A(idx)

There is no case insensitive sorting function in matlab. However, you can always convert your string(s) to all upper or lower case before the sort with upper or lower.
