Description
This function calculates the circular variance from a set of input azimuths.
Usage
1
CircularVariance(azimuths)
Arguments
azimuths
Vector containing the values of the azimuths
Details
One way to get a set of azimuths from X and Y coordinates of the vectors is to use the LoadData function.
Value
The value of the circular variance of all input azimuths. This value ranges between 0 and 1.
