This function calculates the von Mises concentration parameter from a set of input azimuths.

1	VonMisesParameter(azimuths)

azimuths

Vector containing the values of the azimuths

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

The von Mises concentration parameter measures the departure of the distribution from the uniform distribution. If this parameter tends to 0, then the distribution converges to the uniform distribution. If it tends to infinity, then the distribution is concentrated around the mean azimuth.

The von Mises concentration parameter of all input azimuths.
