信号瞬时相关函数的傅立叶变换 wvd
Wigner-Ville 分布(简称 WVD)是典型的二次型变换，它定义为信号瞬时相关函数的傅立
叶变换。
由于在计算中不加窗操作，它避免了时域分辨率和频域分辨率之间的相互牵制。
已证明，对于单分量线性调频信号，WVD 的时频表示能量集中性最优。但也正因为不涉
及窗函数，在分析多分量信号时 WVD 会受到交叉项的干扰。(The Wigner-Ville distribution (WVD) is a typical quadratic transformation, which is defined as the Fourier of the instantaneous correlation function of a signal.
Ye Bianhuan.
Because of no window operation in the calculation, it avoids the mutual restraint between time domain resolution and frequency domain resolution.
It has been proved that for the single component LFM signal, the WVD time frequency representation has the best energy concentration. But it is also because it does not involve.
And window functions, when WVD is used to analyze multi-component signals, it will be interfered by cross terms.)

TFIND
searches for one or more strings (boolean AND) in a text file.
TFIND reports all lines where the string(s) were found (or NOT found
by option).
The search can be limited to a field in a fixed field (i.e. column
oriented) list.
An extended search mode is available, where only letters and digits
are relevant.
Other options:
case sensitive search,
alternative errorlevel with number of hits,
header line with file name, LFN, custom prefix

时频分析工具箱
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)
