作为一个学习Computer Vision的学生,myc经常和矩阵打交道,之前他照着这篇paper写了一个简单的Triangulation的算法,摘录部分如下: function alpha = slower M1 = rand(3); M2 = rand(3); points1 = rand(3,10000); points2 = rand(3,10000); for i = 1:size(points1,2); point1 = points1(:,i);...
function [L,U] = direct_triangulation(A)直接三角分解法求解方程组Ax=b 输入参数：A：方阵A 输出参数：L：下三角矩阵L U：上三角矩阵U n = size(A,1); % 矩阵A的阶数 L = eye(n);U = zeros(n);for k = 1:n-1 for i = k+1:n L(i,k) = A(i,k)/A(k,k);for j =...
代码放在前面 function [V,F]=gen_mesh(bound) % 从离散的边界(顺序的)生成三角网格,返回顶点和面 region=polyshape(bound(:,1),bound(:,2)); tr = triangulation(region); model = createpde; tnodes = tr.Point…
This MATLAB function creates a 2-D or 3-D Delaunay triangulation from the points in a matrix P.
