S: free scaler varible $H$ is known and is a function of$.S.$

W$($s$)$ has $2$ dmensions $(nk$ is degree of freedon and

$k$ is lmear raye for $s.k>n$

The curve fitting equation:

$A_{0}H(s)+A_1[sH(s)]+B_0+[s{B}_1]=-s^{2}H(s)$

$B_0,B_1$ are $n1$ vector ${\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}$
