There's an easier way to create your $Sqs matrix. I tried this with your example and the suggestion by ambrus about matrix multiplication, and it worked.
$Sqs = zeroes($V); $Sqs->diagonal(0,1) .= $S;

    There's an even easier way:

    $Sqs = stretcher($S);
    see PDL::MatrixOps.

[Tanktalus]: My basic problem right now is that if I were willing to move, I could be back in Toronto with a pay raise. We have a number of reasons for not wanting to do that.
