matlab当中的滤波器工具（调用及制作）的使用文档(matlab doc)

广义交义验证的去噪程序包，能够对一维和二维的信号及图像进行处理(PiefLab is a library of Matlab algorithms for wavelet noise reduction PiefLab has several routines for: 1) Wavelet transforms: fast and undecimated, (bi)orthogonal, 1D, 2D. Special attention was paid to fast implementation through Matlab blass routines and polyphase implementation of filter banks. )

一种用于谐波分析的重采样方法，同过matlab仿真实现(For the resampling method of harmonic analysis, Matlab simulation to achieve the same over)

Perl 语言编程 第三版 作者:Larry Wall, Tom Christiansen, and Jon Orwant 译者:何伟平 (The third edition of the Perl programming language: Larry Wall, Tom Christiansen, and Jon Orwant Translator: weipin)

本仿真为电动汽车充电仿真，采用了非隔离式的DC/DC环节(The simulation for the electric car charging simulation, using a non-isolated DC/the DC link)

这是一个PCA的练习题，即主成分分析，用于数据将维，将高维大数据降为低维数据。是一种高效率的数据处理方法。(This is a PCA exercises, namely principal component analysis for data-dimensional, high-dimensional data is reduced to a large low-dimensional data. Is a highly efficient method of data processing.)

Evaluate the value of an arithmetic expression in Reverse Polish Notation. Valid operators are +, -, *, /. Each operand may be an integer or another expression. Some examples: [ 2 , 1 , + , 3 , * ] -> ((2 + 1) * 3) -> 9 [ 4 , 13 , 5 , / , + ] -> (4 + (13 / 5)) -> 6 分析：这一题就是写程序计算逆波兰式的结果，遍历表达式，碰到操作数入栈，碰到操作符就从栈顶取出两个操作数，再将计算后的结果入栈，最后栈中剩余的唯一操作数就是计算结果。(.
