PHASE

Purpose:

Calculates the phase angle of a complex expression.

PHASE(val)

val

A scalar, series or table.

A scalar, series, or table.

phase(1 + i)

returns 0.78539816, or π/4.

W1: 1..5

W2: fft(w1)

W3: angle(w2)

W4: phase(w2)

W3 == {0.000000, 2.199115, 2.827433, 3.455752, 4.084070}

W4 == {0.000000, 2.199115, 2.827433, -2.827433, -2.199115}

W3 returns a value from 0 to 2π.

W4 returns a value from -π to π.

PHASE returns a value from -π to π.

ANGLE returns a value from 0 to 2π.
