VecStatGraphs3D (version 1.6)

MeanModule3D: Calculation of the Mean Module of the angles.

Description

This function calculates the mean module from a set of input coordinates.

Usage

MeanModule3D(coord)

Arguments

coord

Matrix containing the values of the coordinates

Value

The mean module value of all input coordinates.

Details

One way to get a set of coordinates X, Y and Z of the origin position and end position (coordinates X, Y and Z of the vector) or of the colatitude and longitude, it is using the LoadData3D function.
