If I have a matrix A and I want to delete all the rows, y, in A such that y=[1 2 3];
Ex:
A=[ 1 2 3; 4 5 6; 7 8 9; 1 2 3]; y=[1 2 3];
I want to remove all the y vectors from A so that I have:
A=[4 5 6; 7 8 9];

A(all(A==y,2),:)=[]
edit previous versions:
A(all(A==repmat(y,size(A,1),1),2),:)=[]

Error using ==
Matrix dimensions must agree.

try now:
A=[ 1 2 3; 4 5 6; 7 8 9; 1 2 3]; y=[1 2 3];
A(all(A==repmat(y,size(A,1),1),2),:)=[]
