Problem with non-integer order of polylog

Question

Hello,

In the MATLAB documentation for the polylog function, there is an example with non-integer order (first argument):

Li = polylog(-0.2i,2.5)
Li =
  -2.5030 + 0.3958i

However, when I try to reproduce this example, I get the following error message:

"Error using symengine

First argument must be an integer."

Does this mean that I don't have a version of MATLAB updated enough to use the function in this context? I have a MATLAB 2018a.

Also, does anyone know how to find a function's update history in the MATLAB documentation? I couldn't do this alone.

Thanks!

r2019a is the first release to support non-integer orders
