有源低通巴特沃斯滤波器设计根据给定的参数值设计有源滤波器(Active low-pass Butterworth filter design parameters according to the given active filter design)

自己编写的PCA程序，使用简单，标注清晰(I have written the PCA program, simple to use and clearly marked)

实现了简单的windows undoredo操作，并且有自动保护功能(Achieve a simple windows undoredo operation, and automatic protection function)

用于求解组稀疏的matlab代码，可以设置系数为非负。也可以设置分组是否为重叠。(This is a solver for (1) group-sparse basis pursuit model: minimize sum_i w_i*||x_{gi}||_2 subject to Ax = b, x >= 0 (optional),)

二维时域有限差分法：TE波仿真程序，下载即可运行(FDTD—TE wave)

能量谱分析计算,处理信号的时频分析，利用最小二乘算法实现对三维平面的拟合。( Energy spectrum analysis and calculation, When processing a signal frequency analysis, Least-squares algorithm to fit a three-dimensional plane.)

对DOA进行估计的一种较好的方法，能精确地对参数进行估计(Of the DOA estimate of a better way to accurately estimate the parameters)
