实现声音信号倍频程和1/3倍频程的计算，并附有A计权修正的功能(Achieve voice signal octave and 1/3 octave calculations, along with A-weighted correction function)

说明：  function [Sx,f,alpha] = Sa(s,fs,M,N,read_f,del_f) 计算信号的循环谱 [Sx,f,alpha] = Sa(s,fs,M,N,read_f,del_f) 输入： s 序列 fs 采用频率 M 滑动频率窗长 N fft计算点数 read_f 可视频率（一般为载频的整数倍） del_f 可视频率间隔 输出： Sx 信号的循环谱 f 频率轴 alpha 循环频率轴(Cyclosationary Spectrum)

根据牛顿插值原理进行数据的拟合，附有牛顿插值原理和它的matlab的实现方法，有点简单了，但是过程中的好些地方还是值得学习的。(Newton interpolation carried out in accordance with the principle of data fitting, with Newton interpolation matlab principle and its realization method, a bit simple, but in the process of a number of places it is still worth learning.)

步进电机的MATLAB仿真程序，采用了卡尔曼滤波，对定子电流进行估计，并估算出转子的位置和速度(Continuous time extended Kalman filter simulation for two-phase step motor，Estimate the stator currents, and the rotor position and velocity, on the basis of noisy measurements of the stator currents. )
