hello everyone. Now I have compiled a program code to extract the data from the dotted line. But the code has run in a state, I hope you can help to see where the error is. Thank you very much.

CODE:

idx2= MO(:,1)>=min(xx) & MO(:,1)<=max(xx) & MO(:,2)>=centroids(:,2); %The range between abscissa of A1 and A2 is the boundary, which is divided into left and right parts; Note: the center of mass is inside the dune.

dataC=MO(idx2,:);

xx4=dataC(:,1);

yy4=dataC(:,2);

[h,p]=min(yy4);%point_B

B=[xx4(p),h];

ERRO:dataC=[ ]

supplement:centroids is at o.

Hello,

Can you share the code and elaborate your problem?

Thanks

[Wesley]

dc=centroids(:,2);

idx2=MO(:,1)>=-50;

idx3=MO(:,1)<=100;

idx4=MO(:,2)>=dc;

dataC=MO(idx2,:);

dataD=MO(idx3,:);

dataE=MO(idx4,:);

dataF=intersect(dataC,dataD,'rows');%Finding the intersection of dataF,

dataG=intersect(dataF,dataE,'rows');%Finding the intersection of dataG

Can you rotate your data?

What does "the code has run in a state" mean?

And please give all the code including where MO, xx, centroids, etc. get defined.

What is a "dune"? You mean like a windswept pile of sand?

No we don't see the error because you forgot to post it. Post ALL THE RED TEXT. As of now, only Walter has the Crystal Ball Toolbox to see it.
