z = 1+1j
quiver(0,0,real(z),imag(z))
is one way, so that
z = 1+1j;
w = 3-1j;
quiver(zeros(2,1),zeros(2,1),real([z w]'),imag([z w]'))
xlabel('Re(z)'); ylabel('Im(z)');

My command prompt displays only Re(z)
If I write z = 1+5i, the workspace will store z = 1+5i but my command prompt displays it as z = 1.
How do I change this?
TIA

A matrix consists of complex elements. How do I display the elements of the matrix in decimal form rather than scientific form?

If your matrix is a symbolic matrix (its class is sym) use vpa.
If your matrix is a numeric matrix (its class is double or single) use the format function. FYI format only changes how the matrix is displayed, not how it is stored or how it is used in computations.

My problem is I am an doing power system analysis and have voltages in the magnitude near 8000. This is actually a vector. I can display the real and imaginary parts but they come out in scientific notation. I want to display like 7500 volts at an angle of 30.00 degrees For a three-phase system the vector will be three deep each with a desired magnitude and angle.

if complex number is x
fprintf('%f+i%f \n',real(x),imag(x));
