本文给出杨辉三角的几种C语言实现,并简要分析典型方法的复杂度。 本文假定读者具备二项式定理、排列组合、求和等方面的数学知识。 一 基本概念 杨辉三角,又称贾宪三角、帕斯卡三角,是二项式系数在三角形中的一种几何排列。此处引用维基百科上的一张动态图以直观说明(原文链接http://zh.wikipedia.org/wiki/杨辉三角):...
神奇的帕斯卡三角形 今天介绍数学中一个非常神奇数阵“帕斯卡三角形(Pascal's Triangle)”。 帕斯卡三角形,在中国通常称作杨辉三角,又称贾宪三角形、海亚姆三角形、塔塔利亚三角形等,是二项式系数在的一种写法,形似三角形,在中国首现于南宋杨辉的《详解九章算术》得名,书中杨辉说明是引...
In this C Programming example, you will learn to print half pyramid, pyramid, inverted pyramid, Pascal's Triangle and Floyd's triangle.
[LeetCode] 118. Pascal's Triangle Given an integer numRows, return the first numRows of Pascal's triangle. In Pascal's triangle, each number is the sum of the two numbers directly above it as shown: Example 1: Input: numRows = 5 Output: [[1],[1,1],[1,2,1],[1,3,3,1],[...

The scipy.linalg.pascal() function generates Pascal matrices which are square matrices based on Pascal's triangle. These matrices are symmetric and positive definite and which often used in combinatorics, algebra and numerical analysis.Pascal matrices can be created in three forms namely symmetric, ...
8.3C). This element has a total of 18 nodal degrees of freedom, (uxi,uyi) for i = 1–9. The displacement components ux and uy are interpolated by using nine-coefficient polynomials. The following polynomials are obtained from Pascal's triangle by using polynomial symmetry arguments mentioned...
