deriving fractions in matlab

hi, is it possible to derive a fraction? for example: (s+2)/(s^2+7)

thanks.

You can use the symbolic toolbox. If you need to do it more "by hand" then use the chain rule.

You can also use an approximate derivation of your function:

s=0:0.01:100;
y=(s+2)./(s.^2+7);
dy=diff(y)./diff(s)
plot(s(1:end-1),dy)
