If we instead wanted to print from the bottom left to the top right, what would the criteria of the elements that fall on the diagonal be$?($select all that will match the criteria of elements that should be printed$)$

In this week's lecture we looked at the schema of looking at each element of a $2$D array, checking if the element matched a criteria and then taking some action if it matched $($like printing it$).$ The general pattern for this was:

$[$rows$,$ cols$]=$ size$($M$)$

$\%$ look at each row

for r $=1$:rows

$\%$ look at all the columns in this row

for c $=1$:cols

if $($meets criteria$)$

do$\_$action

end

end

end

a condition for identifying the elements that fall on the right diagonal $($starting from top right and going to bottom left$)$ is:

if c $==$ cols $-$ r $+1$

disp$($M$($r$,$c$))$;

end

If we instead wanted to print from the bottom left to the top right, what would the criteria of the elements that fall on the diagonal be$?($select all that will match the criteria of elements that should be printed$)$

r $+$ c $==$ cols $+1$

r $==$ c

r $-$ c $==$ cols $-1$

r $==$ c $-1$
