Carlson_RF {Carlson}

Carlson elliptic integral RF

Description

Evaluate the Carlson elliptic integral RF.

Usage

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

Arguments

x, y, z

real or complex numbers; at most one can be 0

minerror

bound on relative error

Value

A complex number, the value of the Carlson elliptic integral R_F(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_RF(5, 2, 3)
gsl::ellint_RF(5, 2, 3)
