MATLAB: Modify shape of char array

Question

I have this 10×6 character array:

    250F20
    271022
    291124
    2B1326
    2E1429
    2E1532
    2D153C
    2D1743
    2D184D
    2D1954

I would like to convert it to a 10×1 array where each element is a 6-character string. I got what I wanted with a cell array of strings:

cc=cellstr(array);

But I wonder why something like this would not work:

[a,b] = size(array);
for i=1:a
    s(i)= strcat(array(i,1),array(i,2),array(i,2),array(i,3),array(i,4),array(i,5),array(i,6));
end
clear i

Answer 1

Use s{} instaed of s()

[a,b] = size(array);
for i=1:a
  s{i,1}= strcat(array(i,1),array(i,2),array(i,2),array(i,3),array(i,4),array(i,5),array(i,6))
end
