说明：  有关dsp的,有好多子程序,还是不错的,欢迎使用(the dsp, there were a lot subroutine, or good, welcomed the use of)

A Costas loop is a phase-locked loop used for carrier phase recovery from suppressed-carrier modulation signals, such as from double-sideband suppressed carrier signals. It was invented by John P. Costas at General Electric in the 1950s. Its invention was described as having had "a profound effect on modern digital communications".

说明：  快速傅里叶变换FFT通用matlab源程序,众所周知，matlab工具箱里的fft函数是内置的，我们无法看到其源代码，为了学习交流方便，特帖出本人以前用matlab语言写的fft通用matlab源程序，以供初学者学习参考之用！(FFT fast Fourier transform common Matlab source, as we all know, the Matlab toolbox fft function is built-in, we can not see the source code, in order to facilitate the exchange of learning and special TIE out I used to write using the Matlab language fft common source Matlab, for beginners to learn reference only !)

说明：  此程序是OCCAM2D反演程序，可用于大地电磁法中进行二维反演。(This program is occam2d inversion program, which can be used for two-dimensional inversion in magnetotelluric method.)
