A mnemonic device for remembering which subscripts are which, is to think of
the word "arc" which reminds you of
Ar,c or Arow,column
If you need a mnemonic device for remembering which is a row and which is a
column, think of columns on a mansion or building. They go up and down,
vertically, whereas rows go across, left to right, horizontally.
