MATLAB: Error-Reference to non-existent field

image processing

I get an error when executing the code
clc;
clear;
a2=load('DisA.mat')
b2=load('Distance_text1.mat')
c2=load('Distance_c.mat')
d2=load('Distance_Hist.mat')
for i=1:80
    aa=a2.DisA{1,i};%1x96

    bb=b2.Distance_text1{1,i};%1x3
    cc=c2.Distance_c{1,i};%1x4
    dd=d2.Distance_Hist{1,i};%384x1
Features2{i}=[aa,bb,cc,dd'];%1x487
end
save('Features_Distance','Features2')
The error is
Reference to non-existent field 'DisA'.
Error in ==> main at 8
    aa=a2.DisA{1,i};%1x96
the size of each one is
{1×80 cell}

No,
I have checked your file 'DisA.mat' and there is no variable named 'DisA'.
It's better if you try to change your code :
aa=a2.DisA{1,i}
with
aa{i} = a2.D{i}
