Lacoally weighted Regression source code

BST树是一种二叉查找树，但是若是多次插入，BST树便会失衡或者退化成链。于是在BST树的基础上又附加了一个堆的性质，本程序采用最小堆原则。程序代码使用的是VB6.0编写，由于VB中没有指针，所有本程序采用数组模拟，程序一方面实现了treap的算法，另一方面也加了可视化操作界面，非常直观。

在画散点图过程中，我们期望删除一些不需要的点。有时这种点太多，需要批量删除。该工具即根据这一需求，只需要输入删除区域的点坐标，即可实现批量删除。定义域梯形删除法。 用法：必须在Linux命令行下运行，且安装有awk（默认Linux会安装）。

应用背景JPHide 和JPSeek 的源代码！JPHide&JPSeek是一个JPEG图像的信息隐藏软件！-JPHide and JPSeek source code! JPHide & JPSeek is a JPEG image information hidden software!关键技术JPHIDE and JPSEEK are programs which allow you to hide a file in a jpeg visual image. There are lots of versions of similar programs available on the internet but JPHIDE and JPSEEK are rather special. The design objective was not simply to hide a file but rather to do this in such a way that it is impossible to prove that the host file contains a hidden file. Given a typical visual image, a low insertion rate (under 5%) and the absence of the original file, it is not possible to conclude with any worthwhile certainty that the host file contains inserted data. As the insertion percentage increases the statistical nature of the jpeg coefficients differs from "normal" to the extent that it raises suspicion. Above 15% the e

本实验主要涉及解线性方程组的列主元消去法.通过编辑程序,能更深入地了解到列主元消去法的内涵.并且通过计算比较,也可以了解到数据的精度及舍入误差等一系列有关因素.-this study involved solving linear equations of main-element elimination. Through the editorial process, to better understand out to the main yuan elimination connotations. through calculation and comparison, Data can also understand that the accuracy of rounding error and a series of other relevant factors.

DFP, 本程序适用于求解形如f(x)=1/2*x Ax+bx+c二次函数的稳定点 -DFP, this procedure applies to solution of the form f (x) = 1/2* x" Ax+ bx+ c quadratic function of the stable point

用差分方法求解沃尔泰拉方程，此处为一个变元的方程，由于该方程同时含有微分和积分，一般求解有一定的困难。-use of the finite difference method for Volterra equation here as a variable element of the equation, As the same time contain differential equations and integral, the general solution is definitely difficult.
