Dividing Integers

I had to compute the length of arcs of Earth's meridian. I noticed that there was no analytical solution for this so I wrote this very simple function.It computes the arc length of an ellipse centered on (0,0) with radius a (along OX) and radius b (along OY)x(t) = a.cos(t)y(t) = b.sin(t)with...

These programs were developed for fast conversions between binary and decimal integers (there are other programs by fellow Matlab-users, dealing with fractions). They can be useful when the binary numbers are in vector form instead of strings.b2d takes a binary number in the form of an array and...

AQAppStateMachine is designed to assist the development of applications with some fairly intricate state requirements. The idea is that the state itself is stored as an n-bit bitfield, and that the application can define certain ranges of this bitfield to refer to state flags. These flags can be...

The PVM patch for POV-Ray gives POV the ability to distribute a rendering across multiple heterogeneous systems. Using the PVM code, there is one master and many slave tasks. The master has the responsibility of dividing the image up into small blocks, which are assigned to the slaves. When the...

This is a demonstration project which renders ALSA audio samples (16-bit integer streams) using (core) OpenGL. It is intended to serve as sample code for setting up shader-based rendering of basic data-sets (in this case, a ring-buffer of 16-bit integers). The code is currently just "get it done"...
