Functions and Programming

2009
The base installation of R has many built-in functions, including sort and order to arrange vectors or arrays in ascending or descending order; all the standard trigonometric and hyperbolic functions log(base e), log10, exp, sqrt, abs, etc.; and more sophisticated mathematical functions such as factorial, gamma, bessel, fft (Fourier transform), etc ...

Programs and Functions

2013
In this chapter you learned how to create programs and functions from MATLAB scripts. There are several different kinds of functions, and we saw how to take advantage of their different properties. Now that you know how to create programs and functions, you will want to learn more about MATLAB programming to solve challenging and practical problems ...

Functional Programming Techniques

2016
Functional programming is a coding strategy that focuses on the direct use of functions as first-class objects. This means that in a functional program, you are allowed to create, store, and call functions, and otherwise use them as if they were just another variable of the system. Functional code also simplifies programming decisions because it avoids

Programming with variable functions

Proceedings of the third ACM SIGPLAN international conference on Functional programming, 1998
What is a good method to specify and derive imperative programs? This paper argues that a new form of functional programming fits the bill: where variable functions can be updated at specified points in their domain.Traditional algebraic specification and functional programming are a powerful pair of tools for ...

Computational Semantics with Functional Programming

2010
Computational semantics is the art and science of computing meaning in natural language. The meaning of a sentence is derived from the meanings of the individual words in it, and this process can be made so precise that it can be implemented on a computer.

Functional Programming: purrr

2019
A pipeline-based approach to data processing necessitates a functional programming approach. After all, pipelines are compositions of functions, and loops and variable assignment do not work well with pipelines. You are not precluded from imperative programming, but you need to wrap it in functions.

Functional Programming in Scala

2014
This chapter examines the functional programming features of Scala and looks at how they can be used while the next chapter will look at concepts such as Currying and Partially Applied functions.

Pure Functional Programming

2017
A pure function is a function that behaves like a mathematical function: it maps values from one space to another, the same value always maps to the same result, and there is no such thing as a side effect in a mathematical function. The level to which programming languages go to ensure that functions are pure varies, and R does precious little in this

Introduction to Functional Programming

2019
There has been much hype around Functional Programming in recent years. However, Functional Programming is not a new idea and indeed goes right back to the 1950s and the programming language LISP. However, many people are not clear as to what Functional Programming is and instead jump into code examples and never really understand some of the key ideas
