Fix bug in frank matrix for non-integer types

[neil-lindquist]

If the frank matrix is generated for a non-integer type, it errors. The error comes from trying to use p as an index when p is an array of non-integers.

Thanks for the fix. You might add a test case for that.

I added a test case for the case that errors. As a side note, I realized that my initial comment wasn't clear that the error only arises when using the reflected form of the matrix.
