Functional programming in problems of scientific research

Today, the imperative style of programming is the most common, but at the same time is not inviolable dogma, and treats him as opposed to functional programming paradigm. The idea of ​​functional programming based on the intuitive notion of function as a very general mechanism for representation and analysis solutions to complex problems. Mechanism functions well studied by mathematicians, and it allows programmers to follow the updated components that allow you to widely use their mathematical modeling, where a description of how to get the wrong result, which should result
