计算关联维时遇到的问题！

shuilan1984ly

tau=9;ss=6；
data = [---省略---];
N=length(data);
min_m=2;max_m=9;
for m=min_m:max_m
    Y=reconstitution(data,N,m,tau);%reconstitute state space
    M=N-(m-1)*tau;%the number of points in state space
    for i=1:M-1
        for j=i+1:M
            d(i,j)=max(abs(Y(:,i)-Y(:,j)));%calculate the distance of each two           
        end                                %points in state space  计算状态空间中每两点之间的距离
    end
    max_d=max(max(d));%the max distance of all points   得到所有点之间的最大距离
    d(1,1)=max_d;
    min_d=min(min(d));%the min distance of all points   得到所有点间的最短距离
    delt=(max_d-min_d)/ss;%the stepsize of r            得到r的步长
    for k=1:ss
        r=min_d+k*delt;
        C(k)=correlation_integral(Y,M,r);%calculate the correlation integral
        ln_C(m,k)=log(C(k));%lnC(r)
        ln_r(m,k)=log(r);%lnr
        fprintf('%d/%d/%d/%d\n',k,ss,m,max_m);
    end
    plot(ln_r(m,:),ln_C(m,:));
    hold on;
end
fid=fopen('lnr.txt','w');
fprintf(fid,'%6.2f %6.2f\n',ln_r);
fclose(fid);
fid=fopen('lnC.txt','w');
fprintf(fid,'%6.2f %6.2f\n',ln_C);
fclose(fid);
大家帮忙看看，为什么到了end
    plot(ln_r(m,:),ln_C(m,:));
    hold on;
end
这一步就出现错误Undefined function or variable 'd'.
明明是定义了d啊！
请各位高手帮忙啊！

谢谢啊

sigma665

还是进入调试模式，一行一行运行

shuilan1984ly

一行一行运行也不行啊！就命啊，到底错在哪里啊！

ch_j1985

数组d在开始时就应该定义长度吧
