LU decomposition back susbstitution alogrithm for df1b2matrix object.

Parameters:

a	A dmatrix containing LU decomposition of input matrix. .
indx	Permutation vector from ludcmp.
b	A dvector containing the RHS, of the linear equation , to be solved, and containing on return the solution vector .

The implementation of this algorithm was inspired by "Numerical Recipes in C", 2nd edition, Press, Teukolsky, Vetterling, Flannery, chapter 2
