• R : CommutativeRing
• z : Symbol

A package to compute Jacobi continued fractions of Cauchy transforms.

JContinuedFraction : (Distribution(R), UnivariatePolynomial(z, R)) -> ContinuedFraction(UnivariatePolynomial(z, R)) if R has Field

JContinuedFraction(d, z) returns the Cauchy transform as a continued fraction at z.

JContinuedFraction : (Distribution(R), UnivariatePolynomial(z, Fraction(R))) -> ContinuedFraction(UnivariatePolynomial(z, Fraction(R))) if R has IntegralDomain and R hasn't Field

JContinuedFraction(d, z) returns the Cauchy transform as a continued fraction at z.
