congruenceTransform()

bool FFaAlgebra::congruenceTransform ( double **  mat, const FaMat33 &  T, int  N, int  node = 0  )

static

Performs a congruence transformation of a symmetric (3*N)x(3*N) matrix. The transformation matrix consists of a 3*3 submatrix T, which is repeated along the diagonal (when node == 0). If node > 0, the transformation matrix equals the identity matrix, but with the submatrix T inserted on the diagonal at position 3*(node-1)+1 to 3*node.

eccTransform6()

void FFaAlgebra::eccTransform6 ( double  mat[6][6], const FaVec3 &  X  )

static

Performs an eccentricity transformation of a 6x6 element matrix.
