struct block_tri_solu

The last structure type which we have to describe is the block_tri_solu type. This structure is used in connection with the block solver for holding information on a solution of the block-tri-diagonal system of equations. As we discussed in section 2.4 an effective implementation requires that we store both the inverted matrices and the H matrices in the scheme (2.16) a part from the solution block vector. Hence, if we assume a block order of N and (I_block x I_block) block size the block-tri-solution structure has the following form

e
Description

l
Nth order vector of (I_block x I_block) order block matrices for holding the inverted matrices (see the scheme (2.16)).

l
(N-1)th order vector of (I_block x I_block) matrices for holding the $\hspace{0.2ex}\underline{\underline{H}}{}\hspace{0.15ex}_n$ matrices in the scheme (2.16).

l
Nth order block-vector with vector elements of order I_block for holding the block-solution's vector. The block-vector is stored as a (N x I_block) matrix.
