I have a matrix:
u =
0 0 4
0 3 0
0 3 4
2 0 0
2 0 4
2 3 0
2 3 4
I need to delete a row which has value 4 and other values equal to 0.
So, my result should delete the first row, where [0 0 4]. How Can I do?
I did this code below, but it doesn't work.
d=length(u);
if u(1:d,:)==0 & u(1:d,:)==4
u(1:d,:) = []
end
Could anyone help me?

u = [...
0 0 4
0 3 0
0 3 4
2 0 0
2 0 4
2 3 0
2 3 4]
idx = all(u==0 | u==4, 2)
out = u(~idx,:)
