A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies. DCTs are important to numerous applications in science and engineering, lossy compression of audio (e.g. MP3) and images (e.g. JPEG) (where small high-frequency components can be discarded), to spectral methods for the numerical solution of partial differential equations. The use of cosine rather than sine functions is critical for compression, since it turns out (as described below) that fewer cosine functions are needed to approximate a typical signal, whereas for differential equations the cosines express a particular choice of boundary conditions.

介绍LIBSVM的函数，主要是FRUTO的改进版本的LIBSVM(introduce libsvm function)

主要用于地震数据处理中读取segy文件数据，也可以自己合成的数据保存为segy文件。(Mainly used in seismic data processing to read segy file data, you can also save their synthetic data for segy file.)

this code parsing xml tree by reading it and convert it to the matlab format, so we can use a xml document in matlab like an array or struct.
