z = (((-(3)^(0.5) + 3i).^4) * exp((-5i*pi/6))^3)/(2 + 2i)^2; how to convert this into it's polar form and find it's magnitude?

r = abs(z);
theta = atan2(imag(z),real(z));
Also...
r = abs(z);
theta = angle(z);

can this be converted to a single object to be used in calculations. like to be used in a function that accepts polar form arguments. So i dont have to separate all my polar complex numbers similar to the complex(a,b) function but treats the complex number in rectangular form.

Hi Jay,
I'm not quite sure what you are asking, but you can define a complex number simply as:
z = a+b*1i;
z = 3+2*1i; %for example
This is treated by Matlab as a "single object" for use in calculations, and is expressed in rectangular form. Is this what you are asking?
