This is matlab code for SVD based image watermarking

计算时间序列双谱的三维图和二维图，用于研究非线性过程非常管用！(Bispectrum calculation of three-dimensional time series graph and two-dimensional maps, used to study the nonlinear process is very useful!)

数学软件Matlab 学习资料（大学课件）(The Matlab software learning materials (courseware))

说明：  EMD分解matlab小程序，里面包含有EMD工具箱，非常的好用。(EMD decomposes a small matlab program, which contains an EMD toolbox, which is very easy to use.)

说明：  DDC下变频链路搭建，利用FDATOOL工具搭建CIC梳状滤波器、HB半带滤波器以及FIR滤波器；并用VHDL语言实现(DDC down conversion link is built, CIC comb filter, Hb half band filter and FIR filter are built by FDATool tool, and implemented by VHDL language)

说明：  这是用matlab实现的边缘检测图像技术，您可以看看，对新学者有帮助。。。(This is achieved by edge detection matlab imaging technology, you can look at to help the new scholars. . .)

This code is about plotimaging of seismic data.
