mfem::NormalizedVectorCoefficient::NormalizedVectorCoefficient | ( | VectorCoefficient & | A, |
double | tol = 1e-6 |

) |
Return a vector normalized to a length of one.
This class evaluates the vector coefficient A and, if |A| > tol, returns the normalized vector A / |A|. If |A| <= tol, the zero vector is returned.
