class  math_Householder
 This class implements the least square solution of a set of linear equations of m unknowns (n >= m) using the Householder method. It solves A.X = B. This algorithm has more numerical stability than GaussLeastSquare but is longer. It must be used if the matrix is singular or nearly singular. It is about 16% longer than GaussLeastSquare if there is only one member B to solve. It is about 30% longer if there are twenty B members to solve. More...
