[交流] 我这有个matlab程序求解空气污染度（C0、TSP等）与交通流量的关联度，已有1人参与

各位好心人呀，帮忙看一下哪儿有问题？如能解决，感激不尽！
我运行后结果为： $SO^2$ 、 $NO^2$ 、CO、TSP与交通流量的关联度为0.5290、0.7281、0.8428、0.6930，与论文中的结果0.5764、0.6894、0.6817、0.7002不一致！
程序如下：
function r=incident_degree(x0,x1)
x1=[60,66,71,74,57,63,64,75,62,58,67,67,62,52,55,58,58,49,60,34,58,49,75,45,46,22,20,21,27,23];
x0=[0.174,0.131,0.075,0.018,0.046,0.030,0.006,0.051,0.039,0.068,0.077,0.058,0.112,0.049,0.111,0.105,0.022,0.025,0.018,0.026,0.017,0.010,0.018,0.018,0.017,0.003,0.007,0.040,0.040,0.063;
0.050,0.060,0.062,0.033,0.038,0.030,0.031,0.054,0.036,0.062,0.045,0.043,0.027,0.036,0.040,0.038,0.040,0.028,0.030,0.018,0.024,0.020,0.028,0.032,0.021,0.018,0.013,0.015,0.020,0.010;
6.250,6.500,6.220,6.660,4.120,5.040,5.450,7.400,5.870,5.620,6.010,4.620,5.560,3.770,4.230,4.580,6.440,4.670,5.470,3.610,5.680,5.120,9.120,4.030,4.580,2.340,2.100,2.230,2.450,2.010;
0.526,0.566,0.447,0.502,0.339,0.314,0.304,0.412,0.480,0.386,0.424,0.223,0.356,0.534,0.554,0.534,0.774,0.928,0.316,0.445,0.484,0.373,0.373,0.303,0.259,0.166,0.499,0.111,0.277,0.555];
x0_initial=x0./x0(1);
temp=size(x1);
b=repmat(x1(:,1),[1 temp(2)]);
x1_initial=x1./b;
K=0.5;
disp('The grey interconnect degree is:');
x0_ext=repmat(x0_initial,[temp(1) 1]);
contrast_mat=abs(x0_ext-x1_initial);
delta_min=min(min(contrast_mat));
delta_max=max(max(contrast_mat));
a=delta_min+K*delta_max;
incidence_coefficient=a./(contrast_mat+K*delta_max);
r=(sum(incidence_coefficient'))'/temp(2);
