MATLAB中求矩阵非零元的坐标: 方法1: index=find(a); [i,j]=ind2sub(size(a),index); disp([i,j]) 方法2: [i,j]=find(a>0|a<0) %列出所有非零元的坐标 [i,j]=find(a==k) %找出等于k值的矩阵元素的坐标 所用函数简介: IND2SUB Multiple subscripts from linear index. IND2SUB is used to determine the equivalent
Description We all know that a pair of distinct points on a plane defines a line and that a pair of lines on a plane will intersect in one of three ways: 1) no intersection because they are parallel, 2) intersect in a line because they are on top of
