All the vibration weights of nodes are equal; that is, W is the unit matrix. Figure 9 shows the vibration control effect in the range of 1 to 500 rad/s.
In addition, we extend the analysis to compute the inductance per unit matrix using equation (16):
Throughout this paper, we regard the unit matrix [E.sub.n] as the base point of SU(n).
where the superscript number shows the cycle, the subscript number shows the node and [[1.sup.D]] is the unit matrix but only for displacements.
[1], the choice of the unit matrix (of desired order during the solution of the system of linear equations AX = B (by elementary row operations may save the number of iterations considerably.
For a lossless passive network, the complex S-parameter matrix |Mathematical Expression Omitted~ must satisfy the equation |Mathematical Expression Omitted~, where |Mathematical Expression Omitted~ is the unit matrix of the same order as |Mathematical Expression Omitted~, and |Mathematical Expression Omitted~ is the Hermitian conjugate (conjugate transpose) of |Mathematical Expression Omitted~.
