用C++编写的一维和二维快速傅里叶变换程序(Prepared with C++ one-dimensional and two-dimensional fast Fourier transform procedure)

这是一个关于数字预失真功能仿真的matlab程序，效果不错，希望对大家有所帮助。(This is a matlab program about function estimation of digital estimation,and it has a good performance,really hope it can help you.)

大地测量软件，可以计算大地水准面、重力异常、重力梯度等各种物理量(Geodesy software, coordinate transformation, geoid calculation)

F-K域偏移法和相移法偏移程序（C语言）(FK domain migration method and the phase- shift method migration program (C language))

说明：  使用卡尔曼滤波进行目标追踪的matlab源代码(The use of Kalman filter for target tracking matlab source code)

本程序可模拟ND情况下的傅里叶变换，经过验证无误(This program can simulate the Fourier transform of the ND situation, and after the test, the program is correct )

Ⅰ层模型声波波场数值模拟源程序,对各向异性介质中的地震波进行研究，无论是进行野外施工技术研究，还是进 行岩层岩性参数与波动方程之间的关系的研究，或者是进行各向异性介质中地震波 场处理与分析的研究，都离不开各向异性的地震波场数值模拟。(Ⅰ layer model numerical simulation of acoustic wave source for seismic waves in anisotropic media research, whether in carrying out field work research, or to rock lithology parameters and the wave equation of the relationship between research, or to the anisotropy of seismic wave fields in media processing and analysis of the study, are inseparable from anisotropy of seismic wave field numerical simulation.)

数值计算的算法，采用c++实现，移植容易，一定能够用。(Data processing)

说明：  matlab改进的网格算法，work3为主程序(Matlab improve grid algorithm, based procedures work3)

有限元计算软件Abaqus USDFLD子程序在复合材料中强度分析中的应用。(Finite element analysis software Abaqus USDFLD subroutine in the composite material strength analysis applications.)
