There has been a function added in 2013a for this!!

I make it in R2013a,but I don't know the R2012b or other previous versions have this function.

Most of the solutions consider that delim=1char

Hello everyone :)
Just a quick one: the code I provide below here work fine in Matlab (r2019b), so each solution matches the one I'm asked to provide. However, when evaluating the code on Cody, I get "Assertion failed".
Can anyone please explain me if it's a matter of conversion or some details I am missing?
KR, Andrea

out_str=[];

for jj=1:length(in_cell)

tmp=char(in_cell(jj));
c=[tmp,delim];
if jj==1
out_str=c;
else
out_str=[out_str,c];
end
end

I used strjoin(in_string,' ')

passed the first two, third one failed.

This one is kinda hilarious, as (hint here) it may punish you for defining TOO much...
