Hello, when I running the code, a peoblem occurs that is the dimension used for matrix multiplication is incorrect. The problem occurs after running the code :
matches = match(ds1,ds2); (89)
and the matlab shows the error is in the file match.m：
for i = 1 : size(des1,1) (28)
dotprods = des1(i,:) * des2t; （29）

I do really feel confused with the code in the file main.m from 82 to 89:
kp1=kp1(:,1:2);
[kp1,i,]=unique(kp1,'rows','stable');
ds1=ds1(i,:);
kp2=kp2(:,1:2);
[kp2,i,]=unique(kp2,'rows','stable');
ds2=ds2(i,:);
%disp(ds2); % 4x183
matches = match(ds1,ds2);
Could you please explain its function to me , thank you very much.

as the title question.
