The three most common open source technologies for writing data science programs are Python, SciLab, and R. Here's how to write program-defined functions in R.

The main result proved in this paper is that the ratio of the square of a nonnegative convex function to a strictly positive concave function is convex over a convex domain. Some particular cases of ...

Moving from object-oriented to functional programming is a paradigm shift for developers, but these key principles explain why it's worth the effort.

In mathematics, functions like equality, addition, concatenation, etc. have been studied in detail, and so when we use these functions in programming it makes sense to consider what mathematicians ...
