I want to make a loop that keeps replacing its own 'S's with SLSRSLS any N number of times

i want it like this, but in a loop
N = 3;
k = ('S');
k_1 = regexprep(k,{'S'},{'SLSRSLS'});
k_2 = regexprep(k_1,{'S'},{'SLSRSLS'});
k_3 = regexprep(k_2,{'S'},{'SLSRSLS'});
k_4 = regexprep(k_3,{'S'},{'SLSRSLS'});
disp(k_1)
I dont know if there is a easier way to do it, from what i have researched, changing variable names in a loop is not fun

N = 3;
k{1} = {'S'};
for r = 1:N
k{r+1} = strrep(k{r},{'S'},{'SLSRSLS'})
end
Results are k{1}, k{2}, k{3} & k{4}.
k{4} is
{'SLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLS'}

Ran in:
@Mads Albertsen: you get that error message because variable k already exists in the workspace and Simon Chan's code is not robustly written to handle that. Try this instead:
N = 5;
k = {'S'};
for ii = 2:N
k{ii} = regexprep(k{ii-1},'S','SLSRSLS');
end
celldisp(k)
k{1} = S k{2} = SLSRSLS k{3} = SLSRSLSLSLSRSLSRSLSRSLSLSLSRSLS k{4} = SLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLS k{5} = SLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLSLSLSRSLSLSLSRSLSRSLSRSLSLSLSRSLS
If you do not need to store all of those strings (i.e. you only need the last one) then get rid of the cell array entirely.

only needed the last one, so makig k {1} to just k did the trick. but i am curius, if i want to do it with multiple strings and charachters at the same time without them overlapping can it be done in strrep?
