+The files `complex.hpp` and `complex.cpp` contain a partially working complex number class and `test.cpp` holds some basic unit tests.

+You can compile and run with:

+# Morton ordering

 The Morton ordering (or z-ordering) of a matrix lays out the elements
 along a recursive z-shaped curve, as shown in the figure of four
 iterations of the Z-order curve (from

+# Indices
 
 You can compute the Morton index `z` from the x- and y-indices (`i`
 and `j` respectively) by interleaving their bits. An example is shown
 in the table.
