一个空间桁架的优化粒子，与OPENSEES联合应用，求解速度较快，可供参考。(Optimization particle space truss, combined with OPENSEES solved faster, for reference.)

用Matlab仿真实现最小二乘法和总体最小二乘法估计 假设仿真的观测数据 产生，其中 为0均值， 单位方差的高斯白噪声，取n=1,2,....128。 试用TLS，取AR阶数为4，估计AR参数 和正弦波频率；再用SVD-TLS ，估计AR参数 和正弦波频率。 (1)、在仿真中，AR阶数取为4和6。 (2)、执行SVD-TCS时，AR未知。仿真运行至少二十次。 (Simulation using Matlab and the overall least squares least squares estimate assumptions simulated observation data are generated, where 0 mean, unit variance Gaussian white noise, take n = 1,2 ,.... 128. Try TLS, take AR order of 4, estimated AR parameters and the sine wave frequency then SVD-TLS, estimated AR parameters and the sine wave frequency. (1), in the simulation, AR order is taken as 4 and 6. (2), when the implementation of SVD-TCS, AR is unknown. Simulation run at least twenty times.)

利用ARMA 算法估计功率谱的matlab源代码，并画出不同参数情况下的功率谱曲线，内含详细过程。(The ARMA algorithm to estimate the power spectrum matlab source code, and draw the curve of the power spectrum in the case of different parameters, including a detailed process.)

声波方程正演,时间域，加吸收边界条件，可以自己编辑模型(Acoustic wave equation forward, time domain, plus absorbing boundary conditions can edit their own model)
