Subject: Initialize the 'matrix' and 'vector' members in the PETSc wrappers.
X-Git-Tag: v8.5.0-rc1~403^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5cdb2ccf672e2fa6774c06fd06968f98da0d7016;p=dealii.git

Initialize the 'matrix' and 'vector' members in the PETSc wrappers.

These members are of type 'Mat' and 'Vec', which are typedefed to pointers to otherwise
opaque types. Initialize these members to 'NULL'.
