dont want the number if its a part of a complex number

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;

not exactly the method I was going for but it did answer the question, thanks a ton
