Description Usage Arguments Details Value Author(s) References See Also Examples

This function calculates the Mean Direction of a set of input coordinates.

1	MeanDirection3D(coord)

coord

Matrix containing the values of the coordinates

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.

The mean direction value of all input coordinates. The value is expressed in sexagesimal.
