wavelet signal processing

说明：  求解系数矩阵由16阶Hilbert方程组构成的线性方程组， 3、共轭梯度法；(Solving the linear equations consisting of 16-order Hilbert equations of coefficient matrix. 3. Conjugate gradient method;)

介绍matlab原理和功能，并包含了matlab最基本的函数学习(Describes the principle and function of matlab, and contains the most basic function of learning matlab)

Kalman Filtering and theory using Matlab

说明：  本程序运行需一个小时左右。优化准则是旁瓣电平最小。取栅格间距为lemda/2,阵元间距为栅格间距的整数倍。放阵元的位置放1，否则放0(This program should be running an hour or so. Rule of optimization is side-lobe level minimum. Take grid spacing for lemda/2, spacing for grid spacing array (integer times. Put the position of the array (put 1, otherwise put 0 )

以Excel表格保存下来的的交流电压电流波形的离散数据（这些数据从示波器中导出来），本matlab程序可以进行FFT分析，分析电压和电流谐波含量,THD大小。注意，每次只能分析一组数据。(Excel matlab FFT )
