Actually it is a question of notation. For example, mir-lapack
uses ndslice as column-major Fortran arrays. This may cause
some headaches because the data needs to be transposed in mind.
We can think about ndslice as about column-major nd-arrays with
the reversed order of indexing.
The current template looks like
Slice(Iterator, size_t N = 1, SliceKind kind = 1)
If we add a special column-major notation, then it will look
like
Slice(Iterator, size_t N = 1, SliceKind kind = Contiguous,
PayloadOrder = RowMajor)
A PR that adds this feature will be accepted.
Oh, that is news to me. I was under the impression that such a PR
would not be accepted. The prototype you have is exactly what I
had been thinking (that’s what eigen does).
Unfortunately, I don’t think I have the time to ensure everything
works properly with column major. I think my time right now is
better spent on other mir stuff, but it’s good to know that the
only obstacle is someone putting the work in.
