So I'm trying to figure out a way to find the terms that have an imaginary part that is not equal to zero
The array:
sp =
-1.0000 + 0.0000i
-0.8090 + 0.5878i
-0.8090 - 0.5878i
-0.3090 + 0.9511i
-0.3090 - 0.9511i
I tried
x = sp(imag(sp)<0)
as a test, but why doesn't
y = sp(imag(sp)=0)
work

The equality conditional operator in MATLAB is the double equals ==, so
y = sp(imag(sp)==0)
