CircularStandardDeviation: Calculation of the Circular Standard Deviation of the azimuths

Description

This function calculates the circular standard deviation from a set of input azimuths.

Usage

CircularStandardDeviation(azimuths)

Arguments

azimuths

Vector containing the values of the azimuths

Value

The value of the circular standard deviation of all input azimuths.

Details

One way to get a set of azimuths from X and Y coordinates of the vectors is to use the LoadData function.
