说明：  二分法是很重要的，利用二分法求解函数得近似值(Dichotomy is very important. It can be used to get approximate value of function)

用Remez算法设计一个低通滤波器,分别满足性能参数: 滤波器1 滤波器2 滤波器3 采样率Fs: 20kHz 20kHz 20kHz 通带: 0-3 0-4kHz 0-5kHz 带内波纹: 0.1dB 0.1dB 0.1dB 带内衰减: 60dB 60dB 60dB (With the Remez algorithm to design a low pass filter, respectively, to meet the performance parameters: filter 1 filter 2 filter 3 of the sampling rate Fs: 20kHz 20kHz 20kHz pass band: 0-3 0-4kHz 0-5kHz in-band ripple : 0.1dB 0.1dB 0.1dB in-band attenuation: 60dB 60dB 60dB)

MATLAB function that performers delay and sum beamforming on two input signals in the frequency domain.

说明：  自己写的一个计算空间时频分布的程序，可知指定Cohen类分布类型WVD，CWD，PWVD，SPWVD，BJD(himself in a room when calculating the frequency distribution procedures, we can see Cohen category designated distribution type WVD, CWD, Wigner, SPWVD, BJD etc.)

一个运用灰度算法的matlab程序,数据自己设置。这里以房价为例(a matlab program using GRAY arithmetic)

根据型值点反算NURBS曲线的控制点及权因子，正确拟合nurbs曲线(About NURBS curve fitting)
