常用Matlab函数说明文档。收录常用全部函数。(Matlab function commonly used documentation. Indexed all commonly used functions.)

In mathematics, the discrete-time Fourier transform (DTFT) is one of the specific forms of Fourier analysis. As such, it transforms one function into another, which is called the frequency domain representation, or simply the "DTFT", of the original function (which is often a function in the time-domain).(This file includes matlab source code about DTFT and also includes explanation report)

说明：  读取SEGY，SU等格式的地震数据、地质雷达数据。最新版本的matlab源文件，在以前版本做了很大的修改，可以读任意时间段或任意CDP段的数据，使用灵活方便。(Read SEGY, SU format, such as seismic data, geological radar data. The latest version of matlab source files, in previous versions to do a lot of changes, can be read any time or any segment of the CDP data, flexible and convenient.)

直流电测深正演，就电法的一维直流电测深的正演及GUI可视化，可以实现简单的正演及误差的计算和曲线拟合(Electrical sounding speech, the power law DC sounding forward modeling and GUI visualization, you can achieve the simple forward error calculation and curve fitting)

This m-file simulates MPSK (theoretical and simulated) with Gray coding This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).
