Hello,
I have three column vectors of same sizes. I want to remove values 8, 9, 10 from the one vector (B) such that the subequent values in other two vectors (A and C) also get deleted. Similarly, I want to remove value 10 from vector C such that the subsequent values in other two vectors (A and B) also get deleted (means whole row gets deleted). How to perform this task?
My Data:
Result I want:
A = 7x1 double;
B= 7x1 double;
C= 7x1 double;
I want these three variables separately. Thank you.

m=[A,B,C];%need to form matrix
m(ismember(m(:,2),[8 9 10]),:)=[];%entire rows are deleted where 8,9,10 are in column 2 (B)
m(ismember(m(:,3),[10]),:)=[];%enire rows are deleted where 10 is in column 3 (C)
