并且在卷积码编码过程中，添零数为k1*(L-1)=2,(注：L=3)，再对序列进行图示的映射，可通过以下程序实现：(in convolution coding process, the number of zero-Tim k1* (L-1) = 2, (Note : L = 3), then right sequence shows the mapping process can be achieved through the following :)

cpm调制解调实现,关联长度为3，调制指数和进制都可调，解调使用vitebi方法(cpm modem realize, correlation length for the 3, modulation index and the band are adjustable demodulation method using vitebi)

先随机找寻一个合理的初始划分，然后试探将样本从一个群搬到另一个群，如果某次搬动能使准则函数值得到改进的话，则继续搬运，否则废除本次搬运，再继续其他搬运。(Randomly and find a reasonable initial division, and then test the sample from a group of moving to another group, if a move can make the criterion function is worth to improve, it continues to handling, otherwise the abolition of the handling, continue to other handling.)

以软件为主的方法实现QRS波的检测滤波之后的信号一般经过一些 变换以提高QRS波的份量，进而采用一系列阈值进行判别，这些阈值有固定 阈值法，也有可变阈值法。前者由于可能的干扰或高P、高T波的存在，若 其滤波后超过其阈值便会产生假阳性(FP，falsepositive)结果；另外，当心 律失常或QRS波幅度变小，阈值设置过高，会导致漏检产生假阴性(FN， falsenegative)结果。由于固定阈值的这些缺点，有研究者提出了用可变阈 值检测，以提高检测的精确率，所采用的可变阈值包括幅度阈值、斜率阈值 和时间间隔阈值等。(Give priority to with software method for detecting QRS wave signal after some commonly after filtering Amount of transformation in order to improve the QRS wave, then using a series of threshold to distinguish, the threshold value is fixed Threshold value method and variable threshold value method. The former due to the possible interference or the existence of the high P and T waves, if More than the threshold value is created after the filtering false positives (FP, falsepositive results In addition, be careful Law of disorder or QRS wave amplitude decreases, threshold is set too high, can lead to leak to produce false negatives (FN, Falsenegative) results. Due to these disadvantages of fixed threshold, some researchers have proposed using variable threshold Value detection, in order to improve the precision of detection rate, adopted by the variable threshold including amplitude threshold, the slope threshold And the time interval threshold, etc.)

delaunary三角剖分，在数据点较小的情况下，运行结果还算客观，但是数据点大于五万时，运行较慢。(Delaunary triangulation, data point in the case of small, the operation results is objective, but the data points is greater than fifty thousand, is running slower.)
