how to calculate magnitude and phase angle of a complex number

for example -7+13i

how do i calculate and display the magnitude and phase angle of this

Answer 1

[Andrei Bobrov]

z = -7+13i
M = abs(z)    %magnitude
Ph = angle(z) %phase angle
Ph2 = atan2(imag(z),real(z)) %phase angle

[Adrian Nellas]

is Ph = angle(z) in degree already?

[Reza Nikfar]

no this is radian

[Nicholas Cassavaugh]

Yes, it is in radians. You can convert radians to degrees if you wish afterward.

Answer 2

[MALAV DALAL]

z = 1.5+iw
ph = angle(z)

Answer 3

[Dhanush]

x = 1 + i*1;

Magnitude = abs(x);

Phase_radians = angle(x);

Phase_degrees = rad2deg(Phase_radians);
