程序均用matlab编写 ch ex 的文件是信号与系统频谱密度函数或者时移特性的展示 Advanced_Mathematica_picture_zoom是利用二次线性内插值法对彩色图片进行任意倍数的放大 每个程序都含有详细的注释(Programs are written in matlab chex file is spectrum density of signal and system function or moving features of the display Advanced_Mathematica_picture_zoom using quadratic linear interpolation method in arbitrary multiple amplification was carried out on the color images Every program contains detailed annotations)

应用matlab对测井数据进行分析计算，最终实现机械钻速预测(Matlab application for logging data analysis and calculation, and ultimately predict ROP)

这个函数提供灰度拉伸功能，输入图像应当是灰度图像，但如果提供的不是灰度图像的话，函数会自动将图像转化为灰度形式。x1，x2，y1，y2应当使用双精度类型存储，图像矩阵可以使用任何MATLAB支持的类型存储。(This function provides a gray scale stretching function of the input image should be grayscale image, but if not provided, then gray image, the function will automatically be converted to grayscale image form. x1, x2, y1, y2 should use double precision storage, image matrix can store any type of MATLAB support.)

成功实现计算LzehxN算法的程序，本人测试已经通过，性能已基本达到LzehxN算法的性能，需要MATLAB 2009b环境运行，如有问题，欢迎讨论 (The successful implementation of the program to calculate LzehxN algorithm, I have passed the test, need MATLAB2009b operating environment, any questions, please contact me )

Lax-Wendrof法求解一介波动方程，初始条件c=1m/s, x=1-2,u=2m/s(Lax-Wendrof method to solve wave equation)

this program gives detail about detecting the edges of the image
