Description: This paper introduces an affine invariant of trapezia, and the explicit constraint equation between the intrinsic matrix of a camera and the similarity invariants of a trapezium are established using the affine invariant. By this constraint, the inner parameters, motion parameters of the cameras and the similarity invariants of trapezia can be linearly determined using some prior knowledge on the cameras or the trapezia. The proposed algorithms have wide applicability since parallel lines are not rare in many scenes. Experimental results validate the proposed approaches. This work presents a unifying framework based on the parallelism constraint, and the previous methods based on the parallelograms or the parallelepipeds can be integrated into this framework.

Description: This GUI can be used by entering nu at the MATLAB command prompt. The user can either select a function (f(x)) of their choice or a statistical distribution probability distribution function to plot over a user defined range. The function s integral can be evaluated over a user defined range by using: The composite trapezium, simpsons and gauss-legendre rules. This is useful for calculating accurate probabilities that one might see in statistical tables.

Description: 一个数字梯形，选择k条路线，每条路线从第一层的某个数开始，每次进入下一层到达左下或者右下的数字，直到最后一层为止。每条路线不能经过相同的路径，但是可以经过相同的数字节点。 输出一个整数，表示能得到的最大的k条路径经过的数字之和-A digital ladder, the K route, each route the first layer of a number, each time to enter the next layer to reach the left or right next to the number, until the final layer. Each route can not pass through the same path, but can pass through the same number of nodes. Output an integer representing the sum of the number of the largest K paths that can be obtained
