We have no format that handles Kronecker products explicitly. However,
these generally reduce to one-dimensional versions, and are maintained
unassembled I think. However, maybe Barry has a better suggestion.

I wish to perform the matrix-vector multiplication Ax, where A = (I

'kron' is the Kronecker product of two matrices.
Clearly A contains many repeated values. Is there a PETSC format that
can store this matrix efficiently?
If so how does one populate it?
