deg2rad.m

JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the p

function[varargout]=deg2rad(varargin)
%DEG2RAD  Converts degrees to radians.
%
%   [R1,R2,...RN]=DEG2RAD(D1,D2,...DN) converts the input angles from
%   degrees to radians.  Output angles are in the range [-pi,pi].
%
%   See also RAD2DEG, DEG180, DEG360. 
% 
%   'deg2rad --t' runs a test.
