Could you please advise me how I can define the modified Mathieu function in Mathematica? Mathematical has MathieuC and MathieuS functions but does not have modified Mathieu functions Me, Fe, Ge.
Thank you kindly,
Try to take advantage from How to define Mc and Ms Mathieu functions in Terms of MathieuC and MathieuS? The Ce, Se, Fe, and Ge appear in the middle of that text. Me I did not found there. Because it is dated with respect to Mathematica check against your version.
