I know there is a word that represents the most rapidly changed index which starts with "M...", but I can not recall the word even after searching through the internet. So I come here to ask for your help: would you please tell me what the word is.
In computer science, if we have a two-dimensional array (indexed by X and Y), we store the elements of that array in X first order, so the order of the 3X2 array is: [X1,Y1] [X2,Y1], [X3,Y1], and then [X1,Y2],[X2,Y2],[X3,Y2], X is the M... axis; it represents the most rapidly changed indices.
Would you please tell me what the word is? It starts with an M.
