Thin sounds fine to me. Either way I think we need to clean up the docstring to make the different calling styles more obvious. Perhaps we can just add a quick list of variants: q, r = qr(a) # q is m-by-k, r is k-by-n q, r = qr(a, 'thin') # same as qr(a) q, r = qr(a, 'complete') # q is m-by-n, r is n-by-n r = qr(a, 'r') # r is .... a2 = qr(a, 'economic') # r is contained in the upper triangular part of a2 a2, tau = qr(a, 'raw') # ...
