Comparison of complex Numbers

Hi,
I need to test if a certain complex number is already an element of a
vector.
Think of the (complex) vector
nst = [1.2599, -0.62996+1.0911i]
Now, the complex number that I want to test might be
phi(1,1) = 1.2599-0.0000i.
The difference of the imaginary part of those numbers (in this
special case) is
imag(phi(1,1))-imag(nst(1,1)) = -2.2959e-041
Testing
if phi(1, 1) == nst (1,:) doesn't work, since Matlab says that
those numbers aren't equal.
Does anyone know an efficient way to consider those numbers as equal?
Thanks in advance for your replies and for excusing my poor english
;)
Adrian
