VECANGLE: An alternative to atan, returning an arctangent in the
range 0 to 2*pi.
Calling Sequence:
ang = vecmag2(num,dum)
Parameters:
num : Numerator, vector of size (1,nv).
dem : Denominator, vector of size (1,nv).
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]);
