对于信号的包络提取CWDM波形特征新方法的研究，可以有效地提取含杂音信号的包络。便于后续研究。(Extraction of the envelope for the signal waveform characteristics of the new method CWDM research can effectively extract the envelope of the signal with noise. Facilitate follow-up study.)

在实际应用着经常需要求解非线性整数规划或混合规划问题，该领域中的一种常用的算法是分支定界(branch and bound)算法，但是matlab工具箱中没有相关的函数。荷兰Groningen大学的Koert Kuipers编写的的BNB20工具箱可以用来求解一般非线性整数规划问题(In practice, frequent need to solve nonlinear integer programming or mixed programming problem, the area a popular algorithm is the branch and bound (branch and bound) algorithm, but the matlab toolbox functions are not related. Netherlands, Groningen University, prepared the BNB20 Koert Kuipers toolbox can be used to solve general nonlinear integer programming problem)
