MATLAB: How to name states and outputs in level 1 sfunction

I'm not 100% sure, but my best guess is that there isn't a way to name them in Level-1 S-functions. You may find it fairly simple to convert it to a Level-2 S-function however, when you can assign names.

MATLAB: Legend inside a loop

Something like this should work.

for k=1:1:length(c)
    legendstr{1,k} = sprintf('zeta = %f', zetavalue); %legendstr changes size
    legend(legendstr)
end
