names =sort( split(' john alex peter matthew' ))
names =
5×1 cell array
{0×0 char }
{'alex' }
{'john' }
{'matthew'}
{'peter' }

Eliminate the zero-length element, of course.
Starting with a cellstr() or string() array would make more sense than to have them all in one char() vector.

dpb's answer works for any number of names separated by spaces. If your data are arranged differently, we're missing that information. Note that names with spaces will be parsed; example: De Franco.
sort(split('De Franco Cicero Edgars' ))
One small thing to consider with sort() is that it's case sensitive. The two examples below are sorted incorrectly
sort(["adam", "Alan"])
sort(["DeLuca", "Deangelo"])
To get around that sort with all lowercase (or uppercase) and use the index to control the final sorted order
names = ["DeLuca", "Deangelo"];
[~, idx] = sort(lower(names));
names(idx)
