[petsc-users] petsc and matlab

[Barry Smith]

    sopen is compiled by the PETSc makefiles and then put into the directory bin/matlab/

    Did you ./configure PETSc with the option --with-matlab? If not then you will need to run ./configure again and then make again.

   If you did run ./configure with --with-matlab  then please send configure.log and make.log to petsc-maint at mcs.anl.gov  and we'll determine the problem.
