LUSolve Built-in function
  Solves systems of the form LUx = b. Performs a double back substitution to solve a system of linear equations.
Syntax  LUSolve(m,b)
Notes Argument 'm'is the return value of a call to LUDecompose and 'b'is the right-hand side of the system.

Works on matrices only. 'm' is the matrix returned by LUDecompose and 'b' is a column-vector of matching dimension.
Returns a column-vector containing the solution.

Examples
To solve Ax = b, where A is a non-degenerate square matrix:

m = LUDecompose(A);
x = LUSolve(m,b);
