So I know that doing;
Z = [0.5i 1+3i -2.2];
X = real(Z)
would give me
X = 0 1.0000 -2.2000
but what should I do if I only want pure real numbers and not even the real part of the complex number?
for example;
Z = [0.5i 1+3i -2.2];
"..."
would give me
X = 0 0 -2.2000
Thanks any help is appreciated.

Z = [0.5 1+3i -2.2];
Z(~imag(Z))

MATALB convert all numbers float if any number is float in the array as it Auto type cast so we need to convert from the manipulation as shown
flag = abs(real(Z)) == abs(Z);
X = real(Z).*flag;
