Talk:Loop interchange

The two code fragments are swapped at the beginning of the article, incurring great confusion. The result of the "loop interchange" transform is where the column index loop is the inner-most loop. Because in the C language the arrays are row major, and hence elements in the same row are consequtive in memory, hence we must reduce the number of transitions between ROWS as much as possible, meaning that we would like to make the row index loop the outermost.

Agreed. Anyone disagree? Crt389 (talk) 21:48, 15 November 2009 (UTC)

I agree. The two code fragments need to be swapped. —Preceding unsigned comment added by Anantpur (talk • contribs) 10:23, 23 November 2009 (UTC)
