907求多元线形回归方程及预报 一．功能 x1，x2, x3,………..xp为自变量，Y为随机变量， 求线形回归方程 Y= + +…+ + 其中 。。。， 为常数， 是随机变量，且 ―N（0， ） 来描述Y与X的变化规律。并用T检验法检验线形回归是否显著。 如果线性回归显著，可用经验回归平面方程对Y作出预报，并给出预报值的置信区间。 -907 for multiple linear regression equation and a prediction. Functional x1, x2, x3, ... .. xp as variables, Y random variables, linear regression equation for Y = ... which. . . For the constant, random variables and-N (0), to describe the X and Y changes. Using T-test whether linear regression significantly. If the linear regression notable experience available on the return plane equation Y forecasts, and gives the predicted confidence interval.

一凸8 边形P 的顶点顺时针为{v1，v2，… ，v8}，任意两顶点间的线段的权重由矩阵D 给出。 若vi 与vj 是P 上不相邻的两个顶点，则线段vivj 称为P 的一条弦。求P 的一个弦的集合T， 使得T 中所有的弦恰好将P 分割成互不重迭的三角形，且各三角形的权重之和为最小（一 个三角形的权重是其各边的权重之和）。-A convex 8-gon P, vertex clockwise of (v1, v2, ..., v8), any two vertices of the segment between the weight given by the matrix D. If vi and vj is the P is not adjacent to two vertices, then the line segment vivj known as P, a string. Seeking P, a set of strings T, makes the T all the strings just to P divided into non-overlapping triangles, and the weight of each triangle and for the minimum (the weight of a triangle is its weight of each side and) .

此代码可以为BMP图像生成两种效果：生成黑白图像或生成负片图像。代码使用windows.h库中BMP图像的结构。逐像素读取图像。图像表示为以像素为元素的二维数组（自身结构）。程序可以处理24位和32位图像（或其他不使用颜色托盘的图像）。
