用于应用二维数组，生成地震记录剖面，对于地震模型的模拟数据快速生成剖面很有帮助。(A two-dimensional array for application and generates seismic records for seismic model section of analog data generated fast profile is very helpful. )

均值滤波和中值的matlab代码，很有用,比较适合初学者使用。。(meanfilter and medianfilter，pretty good!!)

in this folder contains the import the picture and how to find the effects. how to read the image and how to show the images.

时域有限差分、矩量法做三维平面散射，pml边界条件，并与mur对比(Finite-difference time-domain method of moments to do three-dimensional plane scattering, pml boundary conditions, and compare with mur)

As a consequence, more exact models of devices can be retained for analysis rather than the approximate models commonly introduced for the sake of computational simplicity. A computer icon appears in the margin with each introduction of MATLAB analysis.

功率谱求法，代入函数后使用此方法求解功率谱。(Power Spectral Method.)
