调整pdf的边缘及其行间距大小。首先把pdf保存为图片，然后用此程序调整边缘或行间距大小，把修改后的图片重新整合成pdf。此软件的目的是为了kindle用户编写。因为kindle的屏幕有限，除去多余的边缘和行间距，可以使kindle读书效率更高，减少过多翻页操作。(Adjust the line spacing pdf and the size of the edge. First, save the pdf as a picture, and then use this procedure to adjust the size of the edge or line spacing, the re-integration of the modified images into pdf. The purpose of this software is to kindle the user to write. Because of the limited screen kindle, to remove the extra edge and line spacing can make reading more efficient kindle, to reduce excessive flip operation.)

微分先行PID算法，MATLAB语言编写，仿真效果不错。(Differential first PID algorithm, MATLAB language, simulation results are good.)

本程序为应用小波变换进行信号压缩。由于本程序涉及到了小波变换的函数，因此可能涉及到一些时频分析工具箱的函数。程序中应用db3小波进行3层分解，选用全局阈值进行阈值处理，即对各高频系数使用同一个阈值，进行阈值处理。(This procedure for the application of wavelet transform for signal compression. Since this procedure involves the wavelet transform of the function, it may involve a number of time-frequency analysis function of the toolbox. Procedures for the application of layer 3 to db3 wavelet decomposition, selection of the overall threshold threshold treatment, that is, on the high-frequency coefficients using the same threshold, the threshold for treatment.)

Interpolation refers to the process of converting a sampled digital signal (such as a sampled audio signal) to a higher sampling rate (Upsampling)
