Currently the matrix representation is only supported for uniform grids. The exception is thrown because for nonuniform grids h is None
. I will fix that to make sure that this gives a reasonable error message and for the next release I'll try to work on the matrix representation for non-uniform grids. Thanks for reporting this error!
