ivector ,
const df1b2vector b 
)

LU decomposition back susbstitution alogrithm for df1b2matrix object.

Parameters:
aA dmatrix containing LU decomposition of input matrix. $a$.
indxPermutation vector from ludcmp.
bA dvector containing the RHS, $b$ of the linear equation $A\cdot X = B$, to be solved, and containing on return the solution vector $X$.



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