MATLAB: Using fprintf for complex numbers

Question

Hi, I have

Z1= sqrt(3) * exp((pi*i)/4)
Z2= 2 * exp((pi*i)/6)
Z3= sqrt(3) * exp((3*pi*i)/4)
Z4= 2 * exp(pi*i)
Z5= 2 * exp(-pi*i)

And I would like something like

        Real        Complex
Z1  1.2247 + 1.2247i
Z2 1.7321 + 1.0000i
Z3 -1.2247 + 1.2247i
Z4  -2.0000 + 0.0000i
Z5 -2.0000 - 0.0000i

Using fprintf, I would think…

Thanks for your help!

One Way:

Z1= sqrt(3) * exp((pi*i)/4)
fprintf('%f + %fi',real(Z1),imag(Z1))

More:

Z1= sqrt(3) * exp((pi*i)/4);
Z2= 2 * exp((pi*i)/6);
Z3= sqrt(3) * exp((3*pi*i)/4);
Z4= 2 * exp(pi*i);
Z5= 2 * exp(-pi*i);
disp('     Real   Complex')
fprintf('\nZ1  %.4f + %.4fi',real(Z1),imag(Z1));
fprintf('\nZ2  %.4f + %.4fi',real(Z2),imag(Z2));
fprintf('\nZ3  %.4f + %.4fi',real(Z3),imag(Z3));
fprintf('\nZ4  %.4f + %.4fi',real(Z4),imag(Z4));
fprintf('\nZ5  %.4f + %.4fi',real(Z5),imag(Z5));

Result:
