Matlab处理图形图象的一些处理函数使用方法介绍 (Matlab handle graphics images using a number of treatment function introduction)

LEACH (Low-Energy Adaptive Clustering Hierarchy)

Lagrange插值、Newton插值函数等插值函数，函数为数值分析课本上的例题。(Lagrange interpolation, Newton interpolation function, such as interpolation function, function for the numerical analysis of the textbooks on the sample questions.)

As shown in (5), the inductor current oscillates around a dc value at twice the grid frequency. The PWM technique assumes a constant dc input current and thus,

从物理的角度看，音乐是不同频率，不同时长声波的组合，声波的频率表示不同的音调，声波的时长反映不同的节奏，根据该原理，将不同频率，不同时长的声波进行有序组合，则能成为音乐，利用MATLAB对不同频路信号的组合及分析功能，能够进行简单的音乐合成。(From a physical point of view, the music is different frequencies, not at the same time the combination of the long acoustic wave, the frequency of the acoustic wave which means that a different tone, sound waves reflect the length of time the type of rhythm, based on the principle of different frequencies, not at the same time long waves are conducted orderly composition, to become the music, using MATLAB combination of signals of different frequencies Road and analysis capabilities, able to perform simple music synthesizer.)

说明：  smote算法，用于扩充对数据的采样，当某类样本量较小时，做神经网络对它的类型判断错误率就会较高，所以需要调整采样，语言matlab(smote Algorithms,which used to expand the sampling of data)
