Hi PETSc Experts!
I am updating a Fortran code that use PETSc 3.7 to version 3.9.2 (from
git repository).
Such code declares:
Mat mat
and used it as an integer, for example, to assign an initial value and
test it to know if the matrix has been created by PETSc.
data mat/-1/
if (mat .eq. -1) then
With the new PETSc Fortran modules the compiler complains about this and
stops.
Is there a better way to achieve this? So that I do not have to set an
predefined value to Mat type to test if it was already created by PETSc?
If not, Is there a way to access the value in mat?
Looking at the source code type(tMat) has "v" variable, so could I used
as mat%v?
Thanks for your help,
Hector
