Go Integrals

About

Go Integrals is an implementation of numerical integration algorithms in GoLang. It's mainly an library containing mathematical basic 2D-functions and the integrations algorithms it self.

So far the following functions are available:

• Polynomial (f(x) = c0 + c1*x +c2*x^2 + ... + cn*x^(n-1))
• Exponential (f(x) = a*e^(b*x))

And the following integration algorithms:

• Trapezoidal Rule

There is also a Line "function" to work with a collection of bi-dimensional points. It's possible to calculate the area under a curve formed by those lines, plot a graphic, read and save data, and calculate its length.

Any other function can be use in the algorithm as long as they implement the Function interface.

To Do

• Create develop more functions and add math operations between then
• Plot graphs
• Save and Load points
• Integrate over an slice or array of points

Getting Started

Add the package to your project:

go get github.com/hereisjohnny2/go-integrals

The main.go file in the project root is only for testing integration propose. It will be removed in the future.

Tests

On each polynomial function or integration folder run:

cd functions/exponential
go test
