该代码实现了以2为因子的图像升采样和降采样功能。 降采样包括使用平滑滤波器(with using the averaging filter)和不使用平滑滤波器(without using the averaging filter)两种方法。 升采样包括像素点直接复制(pixel replication method)和线性插值(bilinear interpolatoin method)两种方法。 降采样方法和升采样方法共有4种组合。程序运行后，给出了一个原始图片和四个结果图片。 图片1.原始图片。 图片2.平滑滤波器降采样&像素点直接复制升采样。 图片3.平滑滤波器降采样&线性插值升采样。 图片4.不使用平滑滤波器降采样&像素点直接复制升采样。 图片5.不使用平滑滤波器降采样&线性插值升采样。 (The code to achieve a 2-factor image upsampling and downsampling function. Down-sampling (with using the averaging filter) and do not use smoothing filter (without using the averaging filter) are two ways to use the smoothing filter. Upsampling including the pixels copied directly (pixel replication method) and linear interpolation (bilinear interpolatoin method) two methods. Down-sampling method and liters a total of four combinations of sampling methods. The program is running, it shows a picture of an original picture and four results. Picture 1 original picture.

MATLAB文本分割器，运行程序，输入文件名和分割大小，就可以分割了。 本人比较爱看小说，经常会用到文本分割器，于是用m语言编了一个，分割效率还是挺高的，希望各位会喜欢。(MATLAB version of partition, and run the program, enter the file name and the partition size, you can split it. I am more love stories, often used for text segmentation, and therefore the language used for matlab。 It is so efficiency, and I hope you will enjoy.)

本代码为割线法求解非线性方程组。其调用格式为[r,m]=mulGXF1(F,x0,x1,eps) 其中，F:非线性方程组；x0初始解；x1：初始解；eps：解的精度；m：迭代步数。(The code for the secant method for solving nonlinear equations. Its call format [r, m] = mulGXF1 (F, x0, x1, eps) where, F: non-linear equations x0 initial solution x1: initial solution eps: solution accuracy m: the number of iterative steps.)
