ang.minus: Angular subtraction

In ClusTorus: Prediction and Clustering on the Torus by Conformal Prediction

Description

ang.minus computes element-wise angular subtraction defined as

x - y := Arg(exp(i(x-y)))

Usage

ang.minus(x, y)

Arguments

x, y	angular data(scalar or vector) whose elements are in [0, 2π)

Value

returns a scalar or a vector whose elements are in [-π, π).
