to read matrix data from a file - Add matrix data for the unit test in Matrix Market Exchange Format (.mtx) - Modify the CMake configuration file for HostMatrix in order to copy matrix to the build directory of unit tests
- Enable reading the b vector data from the file - Modify the CMake file to copy vector data to the build directory
…inal matrix which consists of integers - Create a mtx file for storing a vector - Remove commented lines of code and reorganize the unit test
…rices - Add 3 mtx files for storing L, D, and U matrices, respectively - Modify the CMake file to copy L, D, and U matrices over to the build directory

This PR implements a version combination matrix which allows to perform SpMV of multiple submatrices Ie Ax = (B+C+ ...N)x, where A is the combination matrix and B to N are the submatrices. In principle, we could also use Ginkgos combination matrix, but ginkgos combination matrix lacks an implementation of
readwhich we to use the combination matrix as inner matrix type of the distributed matrixThis allows us several improvements in future PRs:
