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.
