Multiply A and B and add them to this; this = beta * this + alpha*A*B or this = beta * this + alpha*B*A.
| sideA | - Which side is A on for the multiplication to B, A*B (Teuchos::LEFT_SIDE) or B*A (Teuchos::RIGHT_SIDE). |
| alpha | - The scaling factor for A * B, or B * A. |
| A | - SerialSymDenseMatrix (a serial SPD dense matrix) |
| B | - SerialDenseMatrix (a serial dense matrix) |
| beta | - The scaling factor for this. |
If the matrices A and B are not of the right dimension, consistent with this, then this matrix will not be altered and -1 will be returned.
