textbook Turbo Pascal

This book is an introduction to two subjects: Matlab and numerical computing. This ¯ rst chapter introduces Matlab by presenting several programs that inves- tigate elementary, but interesting, mathematical problems. If you already have some experience programming in another language, we hope that you can see how Matlab works by simply studying these programs.

this program used to acquire data through pc mic with 8khz sampling frequency. it collects data upto 2sec s duration, (can be varied) and reprodued

文件夹里是最速下降法和牛顿法，这两种方法在最优化中得到了广泛的应用，希望对学习最优化的同学有帮助。(Folder is the steepest descent method and Newton method, these two methods in the optimization has been widely used, I hope to learn to optimize students help.)

Abstract—This paper investigates the performance of a 4-switch

cox 的水印源码, 有多个檔，psnr, RGB to YIQ, YIQ to RGB(cox watermark source, there are multiple files, psnr, RGB to YIQ, YIQ to RGB)

该程序为经典的贝叶斯分类源代码，不仅可以应用于地球物理中的岩性和岩相划分，也可以做储层参数预测！(The source code for classic bayesian classification, the program not only can be used in the lithology and lithofacies division in geophysics, reservoir parameter prediction can also do! )
