Abstract:
Methods are proposed, first, for calculating (in a given domain of complex plane) the eigenvalues of the spheroidal wave equation with complex-valued parameters and, second, for calculating the values of the corresponding functions for complex values of the argument.
Key words:
spheroidal wave functions, eigenvalue problem, recursion formulas, numerical stability.
