function ang = vecangle(num,den) % % VECANGLE: An alternative to atan, returning an arctangent in the % range 0 to 2*pi. % % Calling Sequence: % % ang = vecmag2(num,dum) % % INPUT: % % num : Numerator, vector of size (1,nv). % dem : Denominator, vector of size (1,nv). % % OUTPUT: % ang : Arctangents, row vector of angles. % % Description: % % The components of the vector ang are the arctangent of the corresponding % enties of num./dem. This function is an alternative for % atan, returning an angle in the range 0 to 2*pi. % % Examples: % % Find the atan(1.2,2.0) and atan(1.5,3.4) using vecangle % % ang = vecangle([1.2 1.5], [2.0 3.4]); % % Copyright (C) 2000 Mark Spink % % This program is free software: you can redistribute it and/or modify % it under the terms of the GNU General Public License as published by % the Free Software Foundation, either version 3 of the License, or % (at your option) any later version. % This program is distributed in the hope that it will be useful, % but WITHOUT ANY WARRANTY; without even the implied warranty of % MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
