107 ### Sequential AIJ Sparse Matrices
109 The default matrix representation within PETSc is the general sparse AIJ
112 ### Parallel AIJ Sparse Matrices
114 The AIJ sparse matrix type, is the default parallel matrix format;
117 ### Sequential Block AIJ Sparse Matrices
119 The sequential and parallel block AIJ formats, which are extensions of
120 the AIJ formats described above, are intended especially for use with
125 The routine for creating a sequential block AIJ matrix with `m` rows,
137 for the AIJ format; extension to the block AIJ format is
141 efficient matrix assembly when using the block AIJ format.
143 ### Parallel Block AIJ Sparse Matrices
145 Parallel block AIJ matrices with block size nb can be created with the
176 manual gives an example of preallocation for the parallel AIJ matrix
177 format; extension to the block parallel AIJ case is straightforward.
