rat: Continuous Fractions (Matlab Style)

In pracma: Practical Numerical Math Functions

Continuous Fractions (Matlab Style)

Description

Generate continuous fractions for numeric values.

Usage

rat(x, tol = 1e-06)
rats(x, tol = 1e-06)

Arguments

x	a numeric scalar or vector.
tol	tolerance; default 1e-6 to make a nicer appearance for pi.

Details

rat generates continuous fractions, while rats prints the the corresponding rational representation and returns the numeric values.

Value

rat returns a character vector of string representations of continuous fractions in the format [b0; b1, ..., b_{n-1}].

rats prints the rational number and returns a numeric vector.

Note

Essentially, these functions apply contfrac.

rats(pi)
rat(sqrt(c(2, 3, 5)),  tol = 1e-15)
rats(sqrt(c(2, 3, 5)), tol = 1e-15)
