Integration of One-Dimensional Functions with Double Exponential
Formulas
Installation
You can install the released version of deformula from
CRAN with:
install.packages("deformula")
Description
The double exponential formula has been proposed by the following:
- H. Takahasi and M. Mori, Double Exponential Formulas for Numerical
Integration, Publications of RIMS, Kyoto University, vol. 9 (1974),
pg. 721–741.
which is known as the high precision quadrature. The double exponential
formula is also called tanh_sinh, sinh_sinh and exp_sinh quadrature such
as in Boost C++.
This package only implements tanh_sinh for a finite interval [lower,
upper] and exp_sinh for
.
Example
The example shows the integral of the function
on
:
library(deformula)
f <- function(x, a) exp(-a*x)
deformula.zeroinf(f, a=0.1)

deformula
Integration of One-Dimensional Functions with Double Exponential Formulas
Installation
You can install the released version of deformula from CRAN with:
install.packages("deformula")
Description
The double exponential formula has been proposed by the following:
- H. Takahasi and M. Mori, Double Exponential Formulas for Numerical Integration, Publications of RIMS, Kyoto University, vol. 9 (1974), pg. 721–741.
which is known as the high precision quadrature. The double exponential formula is also called tanh_sinh, sinh_sinh and exp_sinh quadrature such as in Boost C++.
This package only implements tanh_sinh for a finite interval [lower,
upper] and exp_sinh for
.
Example
The example shows the integral of the function
on

library(deformula)
f <- function(x, a) exp(-a*x)
