P1385R1 Linear Algebra

Champion: Bob Steagall

Minute Taker: Davis Herring

Start Overview: 14:00

Break: 15:00

Resume after Break: 15:15

Start Polling: 16:20

POLL: We want 0-based indexing as opposed to 1-based indexing.

NO OBJECTION TO UNANIMOUS CONSENT

Attendance: 20

POLL: We like having separate row_vector and column_vector types in addition to matrix.

Strongly For	Weakly For	Neutral	Weakly Against	Strongly Against
3	0	5	4	4

Attendance: 21

That has no consensus.

POLL: We want explicitly named operations (e.g. dot, outer) in addition to operators.

Strongly For	Weakly For	Neutral	Weakly Against	Strongly Against
8	5	2	1	0

Attendance: 21

That has consensus.

POLL: Define engine/matrix classes in terms of mdspan + storage and mdspan concepts (e.g. extents), and expose an mdspan-esque interface. This implies that fs_ and dyn_ are combined into one template parameterized on extents (which are either static or dynamic).

Strongly For	Weakly For	Neutral	Weakly Against	Strongly Against
6	2	7	0	0

Attendance: 22

That has strong consensus.

End: 16:30
