This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).

Sliders on the figures allow real-time interactive control of the incidence angle,
grating ruling density (lines/mm), wavelength, and diffraction order.

This toolbox contains re-implementations of four different multi-instance learners, i.e. Diverse density, Citation-kNN, Iterated-discrim APR, and EM-DD. Ensembles of these single multi-instance learners can be built with this toolbox
The Cyclone® III PCI development board provides a hardware platform for developing and
prototyping low-power, high-performance, logic-intensive PCI-based designs. The board provides a
high-density of the memory to facilitate the design and development of FPGA designs which need
huge memory storage, and also includes Low-Voltage Differential Signaling (LVDS) interface of
the High-Speed Terasic Connectors (HSTCs) for extra high-speed interface application.
This thesis is devoted to several efficient VLSI architecture design issues in errorcorrecting
coding, including finite field arithmetic, (Generalized) Low-density Parity-
Check (LDPC) codes, and Reed-Solomon codes.
Behavioral models are used in games and computer graphics for
realistic simulation of massive crowds. In this paper, we present a
GPU based implementation of Reynolds [1987] algorithm for simulating
flocks of birds and propose an extension to consider environment
self occlusion. We performed several experiments and
the results showed that the proposed approach runs up to three
times faster than the original algorithm when simulating high density
crowds, without compromising significantly the original crowd
behavior.
These codes require an ASCII input file called input.dat of the following form:
Lower Limit on x Upper Limit on x Final Time
Pressure for x<0 when t=0 density for x<0 when t=0 Speed for x<0 when t=0
Pressure for x>0 when t=0 density for x>0 when t=0 Speed for x>0 when t=0
These codes produce 8 ASCII output files:
density.out. density vs. x
entropy.out. Entropy vs. x
mach.out. Mach number vs. x
massflux.out. Mass flux vs. x
pressure.out. Pressure vs. x
sound.out. Speed-of-sound vs. x
velocity.out. Velocity vs. x
waves.out. A description of the solution in terms of the three waves defined in the book (+,-,0).
