Try this
X=[1,2,3,4,5,6];
idx = find(mod(X,2)==0);
X(idx(1:end-1)) = []

X=[1,2,3,4,5,6,7]
idx = find(mod(X,2)==0);
X(idx(1:end-1)) = []
results in:
X =
1 2 3 4 5 6 7
X =
1 3 5 6 7
you stated:
"...what if I have 7 elements [1,2,3,4,5,6,7] and I still need to get [1,3,5,6]. i need to leave the last even number. not just the last number"
