→Column-major order in Fortran
Line 50:
:Similarly with arrays of matrices. Suppose you had an array A(3,2) which you regarded as a matrix, and then you wanted a collection of such matrices: AHORDE(3,2,100) would give you a hundred such while AHORDE(100,3,2) would give you confusion. But explaining this and schemes for passing a part of such a 3-D array to a subroutine expecting a 2-D array I thought too tricky. On the other hand, not explaining that matrices are normally considered as "row major" in mathematics, ''and that Fortran's MATMUL uses that interpretation'' despite its arrays being the reverse leaves a gap. I have never seen an explanation for this Fortran choice, which it seems to me has only introduced trouble. [[User:Dinosaur|Dinosaur]] ([[User talk:Dinosaur|talk]]) 08:36, 25 October 2016 (UTC)
:: It's probably good, for this site, to move discussions of internals on task pages to task pages that are about exposing internals. That said, I do understand that there's something of a tradition in talking about such details (and, also, that these traditions all too often get historical issues wrong). --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 09:02, 25 October 2016 (UTC)
