Having array trouble

i'm having trouble on manipulating the array form. according to the code below, i try to save the result inform of array so that it can be call outside the loop. but the size of or each row are different and the error appeared as:

Error using vertcat

CAT arguments dimensions are not consistent.

clear; clc;

DG = [0 1 0 0 0; 0 0 1 1 1; 0 0 0 0 1; 0 0 0 0 1; 0 0 0 0 0]
save=[];    
for i = 1:5
  child = find(DG(i,:))
  save = [save; child];
end

can anyone help me to correct this problem, i'm really appreciate it. thank you..

Use cell

save = [save; {child}]

BTW I strongly suggest you to change the variable name, save, because it is one of MATLAB's function name.

Thank you, but how to view the value?? because when i write disp(save) it appeared size of each row.

[Honglei Chen]

you need to use {}, like disp(save{1}) or disp(save{:})

Thank you, for disp(save{:}) cannot been used, matlab appeared error, and i want to list all the result at one time.
