[petsc-users] template function as argument to MatShellSetOperation

2015-01-12 Thread Marco Cisternino 
Hi PETSc users, 
I'm trying to set my matrix multiplication with MatShellSetOperation. 
The question is: is it possible to pass a c++ template function as my matrix 
multiplication to MatShellSetOperation? 
And if yes, how? 
Thanks for any suggestions. 

Marco

No. You will need to write a C wrapper.

  Thanks,
