Description

This function calculates the standard error of the arithmetic mean of a set of input coordinates.

Usage

1

Arguments

coord

Matrix containing the values of the 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.

Value

The standard error of all input coordinates.
