I have a matrix A=[1,2,3;4,5,6]. From this, I want to remove (by row), z=[1,5], to return the matrix B=[2,3;4,6]. I'm trying to use logical indexing to do this, but that returns a vector instead of the matrix B.
if true
B=A(A~=z(:,1))
end

Aout = A';
Aout = reshape(Aout(Aout ~= z(:)'),[],2)';
or
Aout = A';
Aout = reshape(Aout(~ismember(Aout,z)),[],2)';
