dmatrix stores a matrix in compressed sparse row (CSR) format. For computational efficiency, it also store the row indices as well as row start indices.
NOTE: As for sparse matrix, the matrix indices are not modified throughout the whole program. It is possible since matrix-matrix multiplication (except diagonal matrix) is not performed in PCG mode.
| int dmatrix::m |
number of rows
