So if I had an array that contains real numbers and complex number such as this:
r =
0.2876 + 0.3069i
0.2876 - 0.3069i
0.3127 + 0.0000i
And I wanted to change any complex numbers to 0?

This works:
r = [0.2876 + 0.3069i
0.2876 - 0.3069i
0.3127 + 0.0000i];
r(imag(r) ~= 0) = 0
r =
0.0000e+000
0.0000e+000
312.7000e-003
Test for the imaginary part to be not equal to zero to get only the real values. Then set the complex values to zero.

My pleasure.
To replace them with NaN, the assignment becomes:
r(imag(r) ~= 0) = NaN
r =
NaN
NaN
