#include "petscmat.h" PetscErrorCode MatAssemblyEnd(Mat mat,MatAssemblyType type)Collective on Mat
| mat | - the matrix | |
| type | - type of assembly, either MAT_FLUSH_ASSEMBLY or MAT_FINAL_ASSEMBLY |
| -mat_view ::ascii_info | - Prints info on matrix at conclusion of MatEndAssembly() | |
| -mat_view ::ascii_info_detail | - Prints more detailed info | |
| -mat_view | - Prints matrix in ASCII format | |
| -mat_view ::ascii_matlab | - Prints matrix in Matlab format | |
| -mat_view draw | - PetscDraws nonzero structure of matrix, using MatView() and PetscDrawOpenX(). | |
| -display <name> | - Sets display name (default is host) | |
| -draw_pause <sec> | - Sets number of seconds to pause after display | |
| -mat_view socket | - Sends matrix to socket, can be accessed from Matlab (See Users-Manual: Chapter 10 Using MATLAB with PETSc ) | |
| -viewer_socket_machine <machine> | - . -viewer_socket_port <port> | |
| -mat_view binary | - save matrix to file in binary format | |
| -viewer_binary_filename <name> | - Notes: MatSetValues() generally caches the values. The matrix is ready to use only after MatAssemblyBegin() and MatAssemblyEnd() have been called. Use MAT_FLUSH_ASSEMBLY when switching between ADD_VALUES and INSERT_VALUES in MatSetValues(); use MAT_FINAL_ASSEMBLY for the final assembly before using the matrix. |
Space for preallocated nonzeros that is not filled by a call to MatSetValues() or a related routine are compressed out by assembly. If you intend to use that extra space on a subsequent assembly, be sure to insert explicit zeros before MAT_FINAL_ASSEMBLY so the space is not compressed out.
