In my code, I was using polylog, and everything was fine until I update the update 7 recently. Now I am not able to use polylog, and it is showing this error -Error:sym.useSymForNumeric. Error in double/dilog (line 9) Y = sym.useSymForNumeric(@dilog, X. Even i tried to calculate polylog(2,1) and it is showing same error.
I am not able to understand what went wrong after the installation. I am presenting one of the terms of my code, where I have used polylog.
polylog (2, exp (1).^((1/2).*c1).*c2 .*(F3 .^(1/2)+(-1).*F4).^(-1))
I have also attaced the code and one of functiuon (F6.m) in which polylog has been used. while runing this code i am facing above mentioned error.
I am want to emphasis that before update 7, everything was working fine.
I am sure that you can my code
along with all the function attched with it to replicate the error.
