Carlson_RD {Carlson}

Carlson elliptic integral RD

Description

Evaluate the Carlson elliptic integral RD.

Usage

Carlson_RD(x, y, z, minerror = 1e-15)

Arguments

x, y, z

real or complex numbers; at most one can be 0

minerror

bound on the relative error

Value

A complex number, the value of the Carlson elliptic integral R_D(x,y,z).

Note

The function returns a value when x, y or z are negative real numbers, but this value is not the one of the Carlson integral.

Examples

Carlson_RD(5, 2, 3)
gsl::ellint_RD(5, 2, 3)
