libit / News: Recent posts

Last version before major changes in the interface (that will start the 0.3.x series). Also fix many bug and add new functions.

Major modification in the documentation (we use Doxygen now). For the moment the documentation is reduced by comparison with Version 0.2.2, but at least it is synchronised with the library.

This version corrects several bugs and add some new features such as linear algebra tools and so on. Most of the functions are now documented with manpages or html pages.

Hi,

this minor update of libit is composed of several minor updates, a few new functions for matrices, a painful bug in the manpage display, etc.
Note that no RPM package will be released for this version.

Welcome to the second release of libit,

We made a large effort on documentation, and fixed a lot of bugs. Some new tools are also available including an arithmetic coder, convolutional filtering and Markov chain estimation (BCJR/forward-backward and Viterbi algorithm).

Vivien.

This is the first release of libit.
Additionnally to the tools available in the initial CVS import (see previous news item), it adds a parser for configuration files or command line, and the Fourier transform.
There are also a number of small fixes and new vector and matrix functions, especially for handling complex vectors and matrices.

Enjoy,
Vivien.

The libit project has been transfered to sourceforge. It's still under heavy development.

It currently adds the following basic types: vectors, matrices, univariate functions, complexs.
These channel coding tools are provided: rate k/n convolutional codes, bsc and awgn channel, bspk modulation
These source coding tools are provided: variable length codes, scalar/uniform/trellis-coded quantization
These signal processing tools are provided: 1D and separable 2D lifted 5/3 and 9/7 wavelet
It can also read/write pgm images and wav sounds.... read more
