Compute the phase angle in radians of a complex matrix. The general syntax for its use is
p = angle(c)
where c
is an n
-dimensional array of numerical type.
For a complex number x
, its polar representation is given by
and we can compute
Here are some examples of the use of angle
in the polar decomposition of a complex number.
--> x = 3+4*i x = 3.0000 + 4.0000i --> a = abs(x) a = 5 --> t = angle(x) t = 0.9273 --> a*exp(i*t) ans = 3.0000 + 4.0000i
