MathieuCharacteristicA
MathieuCharacteristicA[r, q]
gives the characteristic value 
for even Mathieu functions with characteristic exponent r and parameter q.
Details
- Mathematical function, suitable for both symbolic and numerical manipulation.
- The characteristic value
gives the value of the parameter 
in 
for which the solution has the form 
, where 
is an even function of 
with period 
. - For certain special arguments, MathieuCharacteristicA automatically evaluates to exact values.
- MathieuCharacteristicA can be evaluated to arbitrary numerical precision.
- MathieuCharacteristicA automatically threads over lists.
