Description
Is your feature request related to a problem? Please describe.
Is there any way to represent a sparse matrix given the location of its non zeros
Consider A= kron D I
Where D is the 5 point gem stencil
Describe the solution you'd like
There exists a way to represent a sparse matrix using minimal perfect hashing such that non zeros are represented as the output of a hash function given the flat address
Describe alternatives you've considered
Sparse matrix coming from linear discretized operators can be implemented using minimal perfect hashing such functions

Research direction
No files, tests, or entry points are identified. Start by reviewing the existing sparse-matrix and operator APIs, then determine how a stencil operator and minimal perfect hashing should be represented, including the expected behavior for the kron(D, I) example. Done requires an agreed API, implementation scope, and tests for the requested representation.
