P = angle(Z)
angle(Z)
returns the phase angles, in radians, of the elements of complex matrix Z
. The angles lie between -pi
and pi
.
For complex Z
, the magnitude and phase are given by
and the statementr = abs(Z)
theta = angle(Z)
converts back to the original complexZ = r.
*exp(i
*theta)
Z
.
angle
can be expressed as:
angle(Z) = imag(log(Z)) = atan2(imag(Z),real(Z))
abs
,unwrap
