CORDICbased phase angle
theta = cordicangle(c)
theta = cordicangle(c,niters)
returns
the phase angles, in radians, of matrix theta
= cordicangle(c
)c
, which
contains complex elements.
performs theta
= cordicangle(c
,niters
)niters
iterations
of the algorithm.

Matrix of complex numbers 




Phase angle for doublevalued input and for fixedpointvalued input.
