Hi
I have been trying to debug the following piece of code
to plot Lyapunov Exponents, but getting several errors.
-----------------------------------------------------------------------------------------------
In[1]:=LypHS=Compile[{l, xinit, {n, _Complex}, {ndrop, _Complex}},
      xlist=Drop[
          NestList[-30000l+(1-l)#+l*(2858.16/(#-500)^0.82)&, xinit,
n],
          ndrop+1];
      Apply[Plus, Log[Abs[(1-l)-l(2343.71/(xlist-500)^1.82)]]]/
        Length[xlist]];

Plot[LypHS[l, 10, 5000, 100], {l, 0.0, 1.0}]
-----------------------------------------------------------------------------------------------
Can anyone try to run it and help me to fix these errors ?
Or is any better code is possible for this problem ?
Best regards.
