Question

matlab sparse提示倒数第二行有问题，怎么改？

clc, clear
a(1,2)=32;a(1,3)=37;a(1,4)=21;a(1,5)=3;a(1,6)=24;
a(2,9)=32;a(2,12)=32;
a(3,7)=37;
a(4,8)=21;a(4,10)=21;
a(5,11)=3;
a(6,9)=24;
a(7,13)=42;
a(8,13)=42;
a(9,14)=42;
a(10,14)=42;
a(11,15)=40;
a(12,15)=40;
a(13,16)=42;
a(14,16)=42;
a(15,16)=42;
[i,j,v]=find(a);
tu=sparse(i,j,v,9,9);
[x,y,z]=graphmaxflow(tu,1,16);

Answer 1

% S = sparse(i,j,s,m,n) m,n 是满矩阵时的行列值
% a 阵是 15×16 , 用 9×9 转换时索引值可能会超出范围
tu = sparse(i,j,v,15,16);
