Allocates a SystemMatrix of given type using the given matrix pattern. Values are initialized with zero. If patternIsUnrolled and type & MATRIX_FORMAT_BLK1, it is assumed that the pattern is already unrolled to match the requested block size and offsets. Otherwise unrolling and offset adjustment will be performed.

void paso::SystemMatrix::copyColCoupleBlock | ( | ) |
copies the col_coupleBlock into row_coupleBlock. WARNING: this method uses mpi_requests of the coupler attached to the matrix. No reordering on the received columns is performed. In practice this means that components in row_coupleBlock->pattern->index and row_coupler->connector->recv->shared are ordered by increasing value. Note that send and receive row_coupler->connectors are swapping roles.

matrix may be balanced by a diagonal matrix D=diagonal(balance_vector) if is_balanced is true, the matrix stored is D*A*D where A is the original matrix. When the system of linear equations is solved we solve D*A*D*y=c. So to solve A*x=b one needs to set c=D*b and x=D*y.
