Description: This MATLAB exercise computes the log magnitude of the STFT of a specified frame of speech. Then, using the
same frame of speech, the exercise computes LPC log spectral matches to the speech frame, using the autocorrelation
method, the covariance method, and the lattice method. The four resulting log magnitude responses ( the STFT
of the speech frame and the three LPC analysis methods) are then plotted on a common plot, and compared in
terms of how each LPC analysis method approximates the STFT log magnitude response.

Description: STFT和ST变换的基本函数，和一个stft的一个例程-This code computes the Stockwell transform (S-Transform) of a one dimensional series without for loop, thereby making it computationally fast and simple. S-Transform was proposed in 1996. A nice tutorial on S-Transform can be found here:
djj.ee.ntu.edu.tw/S_Transform.pdf?
File Information Description
The present code is a Matlab function that provides a Short-Time Fourier Transformation (STFT) of a given signal x(n). The algorithm is similar to that of Matlab command “spectrogram”. The result is:
1) stft- a matrix with complex stft coefficients with time across columns and frequency across rows
2) f- frequency vector
3) t- time vector.
swt Discrete stationary wavelet transform 1-D.
swt performs a multilevel 1-D stationary wavelet decomposition
using either a specific orthogonal wavelet ( wname see
WFILTERS for more information) or specific orthogonal wavelet
decomposition filters.

Description: 法国中央科学研究院和美国RICE大学共同开发了时频分析工具箱（matlab emd）
是一款非常好用的时频分析计算工具，它是分析时变非平稳信号的有力工具，matlab 时频分析工具箱提供了时间域与频率域的联合分布信息，清楚地描述了信号频率随时间变化的关系。
其中主要含有四种函数：
信号产生函数，可以产生不停类型的信号，如Chirp信号，bpsk信号等。
时频分析函数，可以计算线性、Cohen类、仿射类非线性分析值函数，例如短时傅里叶变换（STFT），Gabor变换，谱图，Wigner-Ville（WVD）等。
分析处理函数
图形显示函数，如等高线、三维图等。(Time-frequency analysis toolbox)
