imeplula. = SumProduct (A1: A24, B1: B24) в php.
Это то, что я попробовал (но я думаю, что моя формула неверна)
$a = array( 0.72, 0.72, 0.72, 0.72, 0.72, 0.72, 0.72, 0.72, 0.72, 0.72, 0.35, 0.20, 0.05, 0.05, 0.20, 0.35, 0.72, 0.72, 0.72, 0.72, 0.72, 0.72, 0.72, 0.72 );
$b = array( 97.29, 67.68, 66.97, 67.57, 67.80, 94.71, 136.23, 146.77, 139.06, 95.39, 58.66, 48.90, 37.07, 61.31, 95.26, 140.80, 228.09, 318.25, 407.95, 413.11, 409.11, 394.49, 300.57, 162.24 );

$a_total = 0;
$b_total = 0;

foreach( $a as $row ) {
$a_total += $row;
}
foreach( $b as $row ) {
$b_total += $row;
}

$sumproduct = $a_total * $b_total;
