Fixed Point

It stores data in a custom binary file format for speed reasons, and uses fixed-point numbers to handle currency arithmetic so that the potential rounding issues that can result from floating-point arithmetic don???*a*?t occur. The core storage and processing classes are written in generic C++,... Platforms: Windows, Mac, *nix, PHP, BSD Solaris

Mesa is a 3-D graphics library with an API which is very similar to that of OpenGL. To the extent that Mesa utilizes the OpenGL command syntax or state machine, it is being used with authorization from Silicon Graphics, Inc.(SGI). However, the author does not possess an OpenGL license from SGI,... Platforms: *nix

Audio::AMR::Decode is a Perl extension do decode .amr files.

For a full description of the models, refer to the September 2007 MATLAB Digest article.http://www.mathworks.com/company/newslette...sigmadelta.htmlWe present a series of Simulink models to design a high-level behavioral model of a Sigma-Delta ADC. The high-level behavioral model has an Analog... Platforms: Matlab

Recently needed to see the effects of a CIC decimating filter but realized that with my new license of Matlab, I did not have access to the Filter Design Toolbox. This is a quick attempt at a simulation to re-create the effects of CIC-decimation but without the fixed-point access to the... Platforms: Matlab

A Simulink model that generates and displays a simple cosine wave. The model computes the cosine function using the continuous phase method, which is based on Euler's formula for the complex exponential. The cosine generator is provided as a subsystem, which the user can copy-and-paste into other... Platforms: Matlab

Given mean anomaly and eccentricity of an orbit, eccentric anomaly can be calculated using Kepler's Equation. However, the equation is nonlinear, and an iterative technique must be used. This program uses a fixed-point iterative technique to output eccentric anomaly to a user defined tolerance,... Platforms: Matlab

The enclosed files provide a nonlinear algorithm for controlling dynamical systems, particularly in regimes where linear control methods often fail, such as the targeting of states that are distant in phase space from the system dynamics (e.g., a fixed point at the center of a limit cycle). Four... Platforms: Matlab
