PHASE function

Description

PHASE(A) returns the phase angle (or angular component) of the complex number A, expressed in radians. This is Excel's IMARGUMENT function.

The argument A can be a real number, a complex number or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the PHASE function applied to all elements.

$$ phase(a+bi) = asin\left(b / abs(a+bi) \right) $$
