GUI系统进行点运算，即该矩阵对应元素的直接运算。(GUI system point operations, namely the direct calculation of the matrix corresponding to the element.)

说明：  基于人耳识别听觉系统基础的梅尔频谱倒谱系数（MFCC），本次设计采用经过小波包阈值降噪处理的音频文件，提取出其相应的MFCC特征矩阵，以便做接下来的分析！(Based on the Mel spectrum cepstrum coefficient (MFCC) of human ear recognition and hearing system, this design uses the audio file processed by wavelet packet threshold denoising, and extracts its corresponding MFCC feature matrix for the next analysis!)

主要是讲解关于matlab软件的五点三段式的插值处理的m文件(Mainly to explain the five points on three-matlab software interpolation processing m-files)
