# Solve two-point boundary value problems in Ruby with spitzy

A few days ago I programmed a numerical method for the solution for two-point boundary value problems, and today I discovered that I can use MathJax to display mathematical formulas in here (although there are some inconveniences related to the use of underscores). So, here goes another blog post!

# Solve ODEs in Ruby with spitzy

Over the weekend I have written a couple of numerical solvers for one-dimensional initial value problems in Ruby, and added them to my project spitzy.

# Solve an advection equation in Ruby with spitzy

A couple of days ago I started working on a collection of numerical methods for differential equations, wirtten in pure Ruby (I have conviced the professor of my numerical DE class that thats a good idea for my final project in said class).

Recently I got surprised by the behaviour of #permute_columns` in the Ruby gem NMatrix.
