Description Usage Arguments Details Value Author(s) References See Also Examples
This function calculates several statistics for unit and non-unit vectors from a set of input coordinates.
1 | AllAngleStatistics(incr, ndig=4)
|
incr |
Matrix containing the values of the coordinates |
ndig |
Integer value that indicates the decimal places. The default value is 4 |
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 statistics calculated are: Spherical Standar Error, Mean Module, Concentration Parameter, Mean Direction.
The value All Angle Statistics of all input X, Y and Z coordinates.
