A = [0 1 2 3 0 5]
A = A(A~=0)

To delete the first zero entry ONLY:
A(find(A==0,1,'first'))=[];

To delete only the FIRST zero (not all zeros) here is one way.
indexes = find(v == 0);
if ~isempty(indexes) % Only try to delete if we actually FOUND a zero!
v(indexes(1)) = []; % Do the deletion.
end

v(indexes(1) = []; % Do the deletion.

As we've covered the other cases pretty thoroughly...
For the specific input vector OP showed where it is almost certain it is known a priori the first value in the array is zero from outside knowledge of what created the vector in the first place, simply
A=A(2:end);
