MAT_FLUSH_ASSEMBLY

[LECAS Dimitri]

Hi

I'am building a matrice (MPISBAIJ) in two steps, the first one i add  
many contributions with MatSetValue and the flag ADD_VALUES, and the  
last step i put boundary conditions using the flag INSERT_VALUES.

I want to understand how to use MatAssemblyBegin and MatAssemblyEnd.  
Do I have to put between the two steps call to MatAssemblyBegin and  
MatAssemblyEnd with MAT_FLUSH_ASSEMBLY flag and after the last step  
call to MatAssemblyBegin and MatAssemblyEnd with MAT_FINAL_ASSEMBLY  
flag ?


Thanks
