Hello,I would like to know how do I write a complex number in its polar form. Like the image below.

Mycode:

Soperacao = (0.8*250*0.746e3)/(0.87*0.85)
IloadM1 = Soperacao/(sqrt(3)*2.4e3);
IloadM1angle = rad2deg(acos(0.85));
IloadM1 = [IloadM1 IloadM1angle] % is not working, in this way
Iload = IloadM1/(600/(sqrt(3)*2.4))
re = abs(Iload);
thetae = angle(Iload);
Icc3phi_angulo = rad2deg(thetae);
fprintf('Iload = %0.4f /__ %0.2f\n', re, Icc3phi_angulo)

The operation, i want to do:

The ‘image below’ is slightly difficult to read, however the code to do that is easy to write. This is called phasor notation.

phasorr = @(z) [abs(z) angle(z)];
phasord = @(z) [abs(z) rad2deg(angle(z))];
Z = [5 + 1j*2; 5 - 1j*2]
Z = 
   5.0000 + 2.0000i
   5.0000 - 2.0000i
prad = phasorr(Z)
prad = 2×2
    5.3852    0.3805
    5.3852   -0.3805
pdeg = phasord(Z)
pdeg = 2×2
    5.3852   21.8014
    5.3852  -21.8014
Check = [prad(:,1) .* exp(1j*prad(:,2))]
Check = 
   5.0000 + 2.0000i
   5.0000 - 2.0000i
