[petsc-dev] MatISGetLocalMat: need to MatDestroy the returned local matrice ?

[Franck Houssen]

Hello, 

Do I need to MatDestroy the local matrix returned by MatISGetLocalMat ? (the global matrix has been created with MatCreateIS) 

Tried to look in the source tree... But I'am not sure to get the answer: in petsc-3.7.6/src/mat/impls/is/matis.c, MatISGetLocalMat seems to call MatISGetLocalMat_C, but, I can't find MatISGetLocalMat_C in the source tree !?...
