Answer 1

If you transpose the matrix, this is really simple, portable, and idiomatic.

while read -r a b c d e; do
    : stuff with "$a", "$b", etc
done <<____
    1 4 8 8 5
    2 2 9 7 6
    3 3 7 6 7
    4 4 6 5 3
    5 5 5 4 3
____

Notice how the first column enumerates the a values, the second, the bs, etc.
