天线方向图可以看出此算法的性能，该程序把静态方向图与加了旁瓣电平－30db的切比雪夫权方向图相比较(Antenna pattern can be seen the performance of this algorithm, the program direction of the static map with the addition of side lobe level of-30db Chebyshev right direction compared to Figure)

UPSAMPLING AND DOWNSAMPLING

针对光伏电池的MPPT算法模块，本例中的MPPT算法使用的是扰动观察法。(MPPT algorithm module for a photovoltaic cell, the MPPT algorithm used in the present embodiment, the disturbance observer method.)

说明：  利用小波变换实现对故障信号的特征提取 构造特征向量(Wavelet transform feature extraction of fault signals structural feature vector)

这是一个基于matlab的一个pca变换，先从去均值处理，在降维，然后一些列变化(This is a based on the matlab a pca transform, first from to mean processing, on dimensional reduction, and then a few changes )

本程序是基于matlab编程，用于求解平均值，具有快捷高效的特点。(This procedure is based on the MATLAB programming, for solving the average value, has the characteristics of fast and efficient.)
