I want to understand the algorithm of the function "SpheroidalEigenvlaue" in Mathematica 11, especially the code of the following command. 
I am reading the article "Eigenvalues and eigenfunctions of spin-weighted spheroidal harmonics in four and higher dimensions", I think whose more complicate formulas (2.16a)-(2.16g) may be understood from the function "SpheroidalEigenvlaue". Any comments are welcome. Thank you very much!
