mat2ias.m

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

Syntax

    [a,d,A]=mat2ias(C)

Arguments

    C - real 3x3 matrix

Outputs

    a - scalar component

    d - antisymmetric coupling vector

    A - symmetric coupling matrix
