Then, the solution to the problem (7.8.17) is given by the following expressions:
which are obtained the same way that expression (7.8.11) was obtained above.
We note that the matrix now has a form similar to (7.8.13) for . Since the matrix has a form similar to (7.8.14) for all , then columns for all , which follows from expression (3.1.15). It means that the algorithm described in ...
