How do I add space between strings when I am using randperm?

Sorry, I'm not expert but I'm learning.
I've tried some answer regarding how to add space between strings, but it seems that these methods do not apply when using a random generation of string.
If I use matrix concatenation (horzcat): ['A', ' ', 'B'] it will generate the space randomly.
if I use STRCAT then it give me error 'index exceed size of matrix' whatever I do.
This is my code:
string = ['BCDFGHKJLMNPQRSTVWXYZ'];
numRands = length(string);
set_length = 5;
set_string = string( round(randperm(21,set_length))); %21 consonants
Thanks a lot in advance for any help you might provide!

randperm(21, set_length) is going to produce a list of integers. There is no point in round()'ing the integers before using them as indices.

There is a trick to using strcat() to add a space: strcat() will disregard leading or trailing spaces on strings, but will not do so for a cell array of strings. So you can use
set_string1 = string( round(randperm(21,set_length)));
set_string2 = string( round(randperm(21,set_length)));
strcat(set_string1, {' '}, set_string2)
Or, considering that set_string1 and set_string2 are just simple vector of character,
[set_string1, ' ', set_string2]

You could also do this with strjoin (13a or newer)
string = ['BCDFGHKJLMNPQRSTVWXYZ'];
numRands = length(string);
set_length = 5;
set_string = strjoin(cellstr(string(randperm(21,set_length)).').',' ');
