Synopsis

Description

The following functions are defined for complex, where: -- d, m, and a are of type integer and -- x and y are of type complex.

d = abs(x): Returns the absolute value or magnitude of x.
d = norm(x): Returns the square of the magnitude of x. It is faster than abs, but more likely to cause an overflow error. It is intended for comparison of magnitudes.
d = arg(x): Returns the angle of x, measured in radians in the range - to .
y = conj(x): Returns the complex conjugate of x. That is, if x is (real, imag), then conj(x) is (real, -imag).
y = polar(m, a): Creates a complex given a pair of polar coordinates, magnitude m, and angle a, measured in radians.
d = real(x): Returns the real part of x.
d = imag(x): Returns the imaginary part of x.
