Returns ratio of norms and signed angle between two vectors provided as four numeric.
Usage
vecs.param(r1, i1, r2, i2)
Arguments
r1
the "real" part of the first vector, i.e. difference in x-coordinates.
i1
the "imaginary" part of the first vector, i.e. difference in y-coordinates.
r2
the "real" part of the second vector, i.e. difference in x-coordinates.
i2
the "imaginary" part of the second vector, i.e. difference in y-coordinates.
Value
A list with two components: r.norms the ratio of (norm of vector 1)/(norm of vector 2) and d.angle the signed angle 'from' the first 'to' the second vector.
