Section 5.2 [Character r Arrays], , page 68) which h is often the most t natural l method. . For
example:

Nevertheless, there are severalother r functions for concatenating string objects which
canbe usefulin specific circumstances: : char, , strvcat, strcat, andcstrcat. . Finally,
the generalpurpose concatenation functions canbe used: : see [cat], page 410[horzcat],
