What does the following code do?

clear all

close all

clc

M=1; n=0;

while or(M~=0,length(M(:))~=1)

M=input('Enter matrix: ');

if and(M==0,length(M(:))==1)

break

end

n=n+1;

MM{n}=M;

S(n)= sum(M(:));

end

[SS,ind]= sort(S);

Mtmp=MM;

for ii=1:n

MM{ii}=Mtmp{ind(ii)};

end

celldisp(MM);

Talk to the source of the code Asing what uncommented junk code does is difficult to say, especially if we are given no clue as to what it is supposed to do. And, sorry, but this is junk code.

This code prompts the user to input a sequence of matrices (input a scalar 0 to stop) and sorts the matrices according to the sum of their elements.
