K-clustering / Linkeage(K-clustering/Linkeage)

用于提取语音每帧的mfcc函数，将数据保存在cell文件中，可以直接使用cell，也可经过变换，提取到表格中使用(The MFCC function used to extract each frame of speech is saved in cell file. Cell can be used directly or transformed to extract the data into tables)

获得图像局部增强时，每个象素的指数增强系数，指数增强系数有原图像中的灰度值与其周边象素比较获得([Coeff_en_local, lum_mask]=enhance_coeff_local_bilateral(lum_ori,window_r,sigmad,sigmar))

MRS Water Suppression.

将Iris数据集分为2组，每组各75个样本，每组中每种花各有25个样本。其中一组作为以上程序的训练样本，另外一组作为检验样本。为了方便训练，将3类花分别编号为1，2，3 。 　　使用这些数据训练一个4输入（分别对应4个特征），3输出（分别对应该样本属于某一品种的可能性大小）的前向网络。(The Iris data set is divided into two groups each of 75 samples in each group have 25 samples in each flower. One set of sample programs as more training, another group as the test samples. To facilitate training, the three types of flowers were numbered 1,2,3. Training before using these data a 4-input (respectively 4 features), 3 outputs (respectively the possibility should belong to a variety of sample size) to the network.)

输出量通过回路使得占空比D增加或减少，以控制电压的输出或减少，从而达到最大功率点(Output circuit by which the duty ratio D is increased or decreased to reduce the output or control voltage to achieve maximum power point)
