The Audio File Library provides a uniform programming interface to
standard digital audio file formats.
This library allows the processing of audio data to and from audio
files of many common formats (currently AIFF, AIFF-C, WAVE, NeXT/Sun
.snd/.au, IRCAM, AVR, Amiga IFF/8SVX, and NIST SPHERE). The library
also supports compression (currently G.711 mu-law and A-law and IMA and
MS ADPCM) as well as PCM formats of all flavors (signed and unsigned
integer, single- and double-precision floating point).
This program demonstrates some function approximation capabilities of a Radial Basis Function Network.
The user supplies a set of training points which represent some "sample" points for some arbitrary curve. Next, the user specifies the number of equally spaced gaussian centers and the variance for the network. Using the training samples, the weights multiplying each of the gaussian basis functions arecalculated using the pseudo-inverse (yielding the minimum least-squares solution). The resulting network is then used to approximate the function between the given "sample" points.
The EM algorithm is short for Expectation-Maximization algorithm. It is based on an iterative optimization of the centers and widths of the kernels. The aim is to optimize the likelihood that the given data points are generated by a mixture of Gaussians. The numbers next to the Gaussians give the relative importance (amplitude) of each component.

unix或linux下的DNA分析軟件源碼
其功能如下
1. Edit up to 256 peptide or DNA sequences simultaneously.
2. Translates DNA->protein click next to display next frame.
3. Dot matrix plot of any 2 sequences.
4. Rudimentary amino acid statistics (MW and amino acid percentage)
5. Saves matrix plot as PBM image format.
6. Sequence reversal.
7. Creates alignment file for highlight (below).
8. Tab key toggles editing of next sequence.
This is a little console mode utility program which is able to
(de-)compress single files with a static Arithmetic compression
algorithm. You could easily add the RLE/BWT/MFT data
transformation algorithms. Just rip the corresponding classes
out of my HuffComp source code. I won t add these ones in the
next time.
With a worldwide community of users and more than a million dedicated programmers, Perl has proven to be the most effective language for the latest trends in computing and business.
Every programmer must keep up with the latest tools and techniques. This updated version of Advanced Perl Programming from O Reilly gives you the essential knowledge of the modern Perl programmer. Whatever your current level of Perl expertise, this book will help you push your skills to the next level and become a more accomplished programmer.
O Reilly s most high-level Perl tutorial to date, Advanced Perl Programming, Second Edition teaches you all the complex techniques for production-ready Perl programs. This completely updated guide clearly explains concepts such as introspection, overriding built-ins, extending Perl s object-oriented model, and testing your code for greater stability.
