稀疏脉冲反褶积代码,包括高尔消元法解矩阵方程阻,自相关,互相关,褶积,反褶积的代码. 刚参加工作那会儿,上进心也足,爱动脑,编了很多的程序,唯有这一个是我引以为傲的,花了几个星期写的稀疏脉冲(预测)反褶积的代码,放到了现在,觉得也没必要再私藏下去了,不出五年,我都不知道这段代码是干什么的了. 希望对大家有用,方法太简单,所以效果不是太好,请大家修改,如要转载,请记得注明出处. (vc++)

采用数值分析课程中的插值逼近以及曲面拟合方法来估算复杂的函数表达式。(Interpolation approximations and surface fitting methods are used in the numerical analysis course to estimate complex function expressions.)

对信号进傅里叶变换，得到振幅谱和相位谱，并可画出振幅谱和相位谱。(The signal into the Fourier transform, the amplitude spectrum and phase spectrum and amplitude spectrum and phase draw spectrum.)

是ABAQUS有限元模拟软件的子程序，主要研究损伤断裂(a subroutine of ABAQUS for damage and fracture )

J2流动理论加上破坏失效判据的程序，用于ABAQUS中的vumat程序，功能模拟加载到失效破坏的过程(J2 flow theory coupled with damage failure criteria of the program for the vumat ABAQUS program, functional simulation load to failure of the process of destruction)

wilson_theta法计算地震波matlab程序(wilson_theta calculation matlab program of seismic waves)

说明：  一维黎曼问题，一维问题，即激波管问题，是一个典型的一维可压缩无黏气体动力学问题，并有 解析解。对它采用二阶精度两步差分格式进行数值求解。(Riemann problem, One dimensional problem, the shock tube problem, is a typical one-dimensional compressible non viscous gas dynamic problem with analytic solutions. It is solved numerically by two order two step difference scheme.)
