Fenced code in bullet lists with GitHub-flavoured MarkDown??

Fenced code blocks inside ordered and unordered lists

  1. This is a numbered list.

  2. I'm going to include a fenced code block as part of this bullet:

Copy-less bindings of C-generated arrays with Cython

Cython example of exposing C-computed arrays in Python without data copies

The goal of this example is to show how an existing C codebase for numerical computing (here c_code.c) can be wrapped in Cython to be exposed in Python.

The meat of the example is that the data is allocated in C, but exposed in Python without a copy using the PyArray_SimpleNewFromData numpy

Invert matrix by Boost uBlas
/*
The following code inverts the matrix input using LU-decomposition with backsubstitution of unit vectors. Reference: Numerical Recipies in C, 2nd ed., by Press, Teukolsky, Vetterling & Flannery.
you can solve Ax=b using three lines of ublas code:
permutation_matrix<> piv;
lu_factorize(A, piv);
lu_substitute(A, piv, x);
