Calculate the dynamic stiffness using spectral element for a beam in space

it s a camera calibration code written with matlab, and it s very useful for visual manipulation.

地球物理大地电磁测深的正演代码，包含了有限差分、有限元等(magnetotelluric 2D forward finite element program)

SIMO Single Input and multiple out put system is assumed amd MRC maximum ration combining technique is applied at the receiver, hopefully will be helpful for readers.

This part implements the copypaste forgery detection.

a good overview of numerical techniques

评价图形的MSE,SNR，PSNR的GUI。(A　GUI　to evaluate the image s MSE,SNR and PSNR.)

The histogram of the image gives the frequency of occurrence of the gray level.

将复杂网络中的邻接矩阵数据，转换成两列数据，第一列表示有向网络的始点，第二列为末点(The complex network adjacency matrix of data, the data is converted into two, the first column represents the starting point of a directed network, the second column is the end point)

The function impulsive_noise generates non-gaussian noise with inputs of beta, gamma,and the power of noise is 1 in W or 0 in dB. The noise can be defined either real or complex. The other functions generate QAM symbol and insert a vector to another vetor with specific locations
