线性调频信号是获得高分辨常用信号，文件是通过线性调频信号来进行脉冲压缩处理，获得高分辨。(Chirp signal is to obtain a high-resolution commonly used signal file chirp signal pulse compression processing to obtain high-resolution.)

判断一个样本服从那种分布的例程,包含正态分布、指数分布等(judge which distribution did a sample follows)

Calculates the result of Euler s Phi funtion for any natural number less than 10^18.

线性代数实践及MATLAB入门 本书是根据“用软件工具推向线性代数教学”的指导思想，参照美国1992-1997国家科学基金项目ATLAST的思路，编写成的线性代数补充教材，其目的是补充我国现有教材的的缺陷。它分为两篇，第一篇介绍线件代数所用的软件工具MATLAB语言，第二篇介绍线性代数实践。本书可作为大学本科线性代数的配套教材，也可作为广大理工、经管领域教师、工程师和研究生的参考读物。(Introduction to Linear Algebra practice and matlab This book is based on the guiding ideology"use of software tools into the teaching of linear algebra," , with reference to the ATLAST ideas of U.S. National Science Foundation(1992-1997) , written as a linear algebra supplementary materials, the purpose is to supplement our existing materials defects. It is divided into two parts, the first introduces line of pieces of software tools used in algebraic MATLAB, the second introduces linear algebra practice. )

编写了龙格现象中举例的函数（1/（1+x^2））的三次样条插值图像和原图像的比较，此程序简单适用。(Prepared Runge phenomenon, for example a function of (1/(1+ X ^ 2)) of cubic spline interpolation image and the original image compared to a simple application of this procedure.)
