Notes: By default if you insert values into the lower triangular part of the matrix they are simply ignored (since they are not Many brstored and it is assumed they symmetric to the upper triangular). If you call MatSetOption(Mat,MAT_IGNORE_LOWER_TRIANGULAR,PETSC_FALSE) or use Many brthe options database -mat_ignore_lower_triangular false it will generate an error if you try to set a value in the lower triangular portion.
