MatAssemblyEnd

Completes assembling the matrix. This routine should be called after MatAssemblyBegin().

Synopsis

#include "petscmat.h" 
int MatAssemblyEnd(Mat mat,MatAssemblyType type)
Collective on Mat

Input Parameters

mat - the matrix
type - type of assembly, either MAT_FLUSH_ASSEMBLY or MAT_FINAL_ASSEMBLY

Options Database Keys

-mat_view_info - Prints info on matrix at conclusion of MatEndAssembly()
-mat_view_info_detailed - Prints more detailed info
-mat_view - Prints matrix in ASCII format
-mat_view_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)
-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.
