Program works fine by itself, but when I call it to another m file the error below occurs.

Command Window :

Undefined function or variable 'ang'.
Error in Degree_to_NorthAZM (line 26)
DTNA =[ang min sec];

Editor :

function [DTNA] = Degree_to_NorthAZM(angle, Direction)
% This function converts angle = [Degree Minute Second] into North AZM
% Direction 1, 2, 3 and 4 are respectively NW, NE, SE and SW
if Direction == 1
      ang = 359 - angle(1,1);
      min = 59 - angle(1,2);
      sec = 60 - angle(1,3);
elseif Direction == 2
      ang = angle(1,1);
      min = angle(1,2);
      sec = angle(1,3);
elseif Direction == 3
      ang = 179 - angle(1,1);
      min = 59 - angle(1,2);
      sec = 60 - angle(1,3);
elseif Direction == 4
      ang = 180 + angle(1,1);
      min = angle(1,2);
      sec = angle(1,3);
end % End of If else loop
DTNA =[ang min sec]; % Function output
end % End of Function
