           Summary: Typo

These two should agree:

$string1= Formula("$c[0]*$d[0] * x + $c[1]*$d[1] * y")->reduce;
$string2= Formula("$c[2]*$d[2] * x + $c[3]*$d[3] * y")->reduce;
$string3= Formula("$c[4]*$d[4] * x + $c[5]*$d[5] * y")->reduce;
$string4= Formula("$c[6]*$d[5] * x + $c[7]*$d[7] * y")->reduce;

$A = Matrix([
[ $c[0] * $d[0], $c[1] * $d[1] ],
[ $c[2] * $d[2], $c[3] * $d[3] ],
[ $c[4] * $d[4], $c[5] * $d[5] ],
[ $c[6] * $d[5], $c[7] * $d[6] ],
]);

$A should probably be changed to:
$A = Matrix([
[ $c[0] * $d[0], $c[1] * $d[1] ],
[ $c[2] * $d[2], $c[3] * $d[3] ],
[ $c[4] * $d[4], $c[5] * $d[5] ],
[ $c[6] * $d[5], $c[7] * $d[7] ],
]);
