many matlab script ,i colect many things about mathmatics and many method of math problem

function [A]=guangduyouxian(l,linjie0,ver)
    N=size(linjie0(:,1));
        for j=1:N
            for i=1:N
                if  ver(linjie0(i,1))+ver(linjie0(i,2))==1 
                    ver(linjie0(i,1))=1;
                    ver(linjie0(i,2))=1;
                    A(l,:)=linjie0(i,:);
                    l=l+1;
                    guangduyouxian(l,linjie0,ver);
