 ## Computational Methods for Numerical Analysis is Out Now!

My new book Computational Methods for Numerical Analysis with R came out today from Chapman & Hall/CRC Press. This book is a long-standing project of mine–originally started in 2001, and then using Octave as the base language. As the world didn’t need yet another book on doing numerical analysis in

## Announcing Computational Methods for Numerical Analysis

For about two years, I’ve been working on a book called Computational Methods for Numerical Analysis with R (CMNA), which will present an outline of numerical analysis topics with original (and simplified) implementations in R at a level appropriate for a graduate student or advanced undergraduate. Last night, I sent

## The Wave Equation in R

The wave equation is a classic example of a partial differential equation. It comes in several variants and has applications beyond the name. In principle, the wave equation describes the path of a wave traveling through a medium. For a one-dimensional wave equation, this describes a wave traveling on a

## CMNA v0.1.0 Released

Some of you know this, but just about a year now, I have been working on a book called Computational Methods for Numerical Analysis with R. This project, completed in my copious free time, was something of a dream project. Since I was an undergraduate mathematics major, where I found

## Euler Method in R for the Initial Value Problem

During differentiation, the value of whatever vertical shift is present is lost as a result of the elimination of the constant term, which has a derivative of 0. We normally acknowledge this when integrating a function by adding a constant, the constant of integration, to an indefinite integral. This is
