自己编写的曲线拟合程序，供大家一起参考，一起学习努力(themselves prepared curve fitting procedures for everyone reference and learning efforts)

least significant bit insertion is done using matlab..data is hidden in the least significant bit of carrier file.

说明：  异步电机矢量控制程序，通过调节转矩，电机可以具有快速动态响应(By adjusting the torque, the motor can have fast dynamic response)

说明：  Matlab教程，初学者很好的学习材料。拿来分享。(Matlab tutorial for beginners good learning materials. To be shared.)

用窗函数法设计线性相位FIR低通滤波器。要求通带截止频率ωc=π/4，单位脉冲响应h(n)的长度N=23。绘出h(n)及其幅频响应特性曲线(Window function with linear phase FIR design a low pass filter. Required pass-band cutoff frequency ωc = π/4, unit impulse response h (n) of length N = 23. Plot h (n) and frequency response curves)

二分法 插值 通过每次把f(x)的零点所在小区间收缩一半的方法，使区间的两个端点逐步迫近函数的零点，以求得零点的近似值(Each time the interpolation dichotomy by f (x) between zero shrinkage area where half of the ways in which the two endpoints interval function gradually approaching zero, in order to achieve an approximation of zero)
