Integrals.jl: Unified Integral Approximation Interface

Integrals.jl is a unified interface for the numerical approximation of integrals (quadrature) in Julia. It interfaces with other packages of the Julia ecosystem to make it easy to test alternative solver packages and pass small types to control algorithm swapping.

Installation

To install Integrals.jl, use the Julia package manager:

using Pkg
Pkg.add("Integrals")
