# geo2arideg

## PURPOSE

GEO2ARIDEG converts geographic angles to arithmetic angles.

## SYNOPSIS

function [ariAng] = geo2arideg(geoAng)

## DESCRIPTION

    GEO2ARIDEG converts geographic angles to arithmetic angles.
     geoAng is a scalar, vector, or matrix of geographic angles in
     degrees, i.e., geographic headings (North = 0, with angles
     positive clockwise) ariAng is an output of size(geoAng) with
     angles converted to angles such as those produced with atan()
     or atan2().

     EXAMPLE USAGE
       geoAng = 300
       [ariAng] = mcsADCP.geo2arideg(geoAng)
       ariAng =

       150
