Confluent hypergeometric functionController: CodeCogs
Computes the confluent hypergeometric function
Accuracy:Tested at random points (a, b, x), all three variables ranging from 0 to 30. <pre> Relative error: arithmetic domain # trials peak rms DEC 0,30 2000 1.2e-15 1.3e-16 IEEE 0,30 30000 1.8e-14 1.1e-15 </pre> Larger errors can be observed when b is near a negative integer or zero. Certain combinations of arguments yield serious cancellation error in the power series summation and also are not in the region of near convergence of the asymptotic series. An error message is printed if the self-estimated relative error is greater than 1.0e-12.
