Reconstruction of a 3x3 real interaction matrix C between real vectors u and v from its isotropic-antisymmetric-symmetric decomposition: a*(u'*v) + d'*cross(u,v) + u'*A*v = u'*C*v

Syntax

    C=ias2mat(a,d,A)

Parameters

   a - scalar component

   d - antisymmetric coupling vector

   A - symmetric coupling matrix

Outputs

   C - real 3x3 matrix
