Dear All
I have A = {[1 2]; [2 2]; [2 1 3]; [1 1 3] }, a cell array contains several vectors with various length.
Input :
[1 2]
[2 2]
[2 1 3]
[1 1 3]
and I want to sort this cell array according to ascent order of each element, and regardless the length.
What I expect to have is
[1 1 3]
[1 2]
[2 1 3]
[2 2].
What I use is convert vector to string, and then sort the strings.
=====
% each number should have the same length in string.
ind = cellfun(@(x) num2str(x,'%05.f,'), A, 'UniformOutput',false);
=====
However, num2str is expensive. Do you have any other good idea to do this? Thanks!!!
