I'm struggling to grasp in a string all the values of a dicrete

hint?
Things must look like this:
string col_title = ""
discrete groups
matrix val = values(groups)
loop i = 1..rows(val) --quiet
col_title += val(i) # of course, it doesn't work
col_title += " "
endloop
<hansl>
matrix vals = {0,5,10,15,20}' # just an example
string col_titles = ""
string valstr
loop i=1..rows(vals)
sprintf valstr, "%g ", vals[i]
col_titles += valstr
endloop
printf "Got '%s'\n", col_titles
