K邻域模式识别方法 KNN算法不仅可以用于分类，还可以用于回归。通过找出一个样本的k个最近邻居，将这些邻居的属性的平均值赋给该样本，就可以得到该样本的属性。更有用的方法是将不同距离的邻居对该样本产生的影响给予不同的权值(weight)，如权值与距离成正比。(k-Nearest Neighbor algorithm )

产生固定周期数的正弦脉冲信号 使用该函数时必须预先设定如下参数：正弦波的频率Fp，构成输出脉冲的正弦波的周期个数Nc，脉冲幅度A每个周期的采样点数smp。函数有两个输出：脉冲波形，以响亮sinpulse的形式输出，采样周期dt。(Produce a fixed number of cycles of the sine pulse signal         Use this function must be pre-set the following parameters: a sine wave of frequency Fp, constituting the output of the pulse cycle of the sine wave of the number Nc, the sampling points for each cycle of the pulse amplitude A smp. The function has two outputs: output pulse waveform, the a loud sinpulse form, the sampling period dt.)
