Here aand in other places, In the ViennaCL (both modules) Unit tests, the signs are flipped when adding random data to matrices.

    // add some sparse data with a 20% threshold
    mxA := { (_, _, v) => if (r.nextDouble()  .20) r.nextDouble() else v }
    mxB := { (_, _, v) => if (r.nextDouble() < .20) r.nextDouble() else v }
