This week we have RegEx Processing, Infinite Types, and some mathy code sample blogs I’ve stumbled upon.

Steve Horsfield has completed his F# Regular Expression Processor

This post completes this mini-series on regular expression processing in F#. You can find the complete source code here as well. It has been a good practice for me and I hope you have found the series useful.

StackOverflow: Are Infinite Types (aka Recursive Types) not possible in F#?

I was chatting with Sadek Drobi on twitter when he brought up that F# didn't seem to support Infinite Types. It turns out that in C# you can do something along these lines […] However, after some experimentation on both our parts, we determined that the same in F# seems impossible both implicit and explicitly.

Code Snippets and Examples

While I don’t know who they are run by, I’ve happened upon a couple of blogs which frequently have interesting F# code snippets posted:

The Mad Economist
F# Matrix Inversion (1) - Linear Decomposition
F# Matrix Inversion (2) - The Inverse
F# - Ordinary Least Squares (OLS)
F# - OLS (R-Square) - Array2D.init

F# Code
Lambda Calculus Normal Order Reducer
GroupBy Rx Combinator
Reactive Linq in F#
