我用easymat做出如下的矩阵:
\[
\left[
\begin{MAT}(@){c}
\dot{u}\\
\dot{v}\\:
\dot{p}\\
\dot{q}\\:
\dot{\phi}\\
\dot{\theta}\\:
\tau_f\dot{a}\\
\tau_f\dot{b}\\:
\dot{w}\\:
\dot{r}\\
\dot{r_{fb}}\\:
\tau_s\dot{c}\\
\tau_s\dot{d}\\
\end{MAT}
\right]=
\left[
\begin{MAT}(@){cc:cc:cc:cc:ccc:cc}
X_u & 0 & 0 & 0 & 0 & -g & X_a & 0 & 0 & 0 &
0 & 0 & 0 \\
0 & Y_v & 0 & 0 & -g & 0 & 0 & Y_b & 0 & 0 &
0 & 0 & 0 \\:
L_u & L_v & 0 & 0 & 0 & 0 & 0 & L_b & L_w & 0 &
0 & 0 & 0 \\
M_u & M_v & 0 & 0 & 0 & 0 & M_a & 0 & M_w & 0 &
0 & 0 & 0 \\:
0 & 0 & 1 & 0 & 0 & 0 & 0 & 0 & 0 & 0 &
0 & 0 & 0 \\
0 & 0 & 0 & 1 & 0 & 0 & 0 & 0 & 0 & 0 &
0 & 0 & 0 \\:
0 & 0 & 0 & -\tau_f & 0 & 0 & -1 & A_b & 0 & 0 &
0 & A_c & 0 \\
0 & 0 & -\tau_f & 0 & 0 & 0 & B_a & -1 & 0 & 0 &
0 & 0 & B_d \\:
0 & 0 & 0 & 0 & 0 & 0 & Z_a & Z_b & Z_w & Z_r &
0 & 0 & 0 \\:
0 & N_v & N_p & 0 & 0 & 0 & 0 & 0 & N_w & N_r &
N_{rfb} & 0 & 0 \\
0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & K_r &
K_{rfb} & 0 & 0 \\:
0 & 0 & 0 & -\tau_s & 0 & 0 & 0 & 0 & 0 & 0 &
0 & -1 & 0 \\
0 & 0 & -\tau_s & 0 & 0 & 0 & 0 & 0 & 0 & 0 &
0 & 0 & -1 \\
\end{MAT}
\right]
\left[
\begin{MAT}(@){c}
u\\
v\\:
p\\
q\\:
\phi\\
\theta\\:
a\\
b\\:
w\\:
r\\
r_{fb}\\:
c\\
d\\
\end{MAT}
\right]+
\left[
\begin{MAT}(@){cc:cc}
0 & 0 & 0 & 0\\
0 & 0 &Y_{ped}& 0\\:
0 & 0 & 0 & 0\\
0 & 0 & 0 &M_{col}\\:
0 & 0 & 0 & 0\\
0 & 0 & 0 & 0\\:
A_{lat}&A_{lon}& 0 & 0\\
B_{lon}&B_{lon}& 0 & 0\\:
0 & 0 & 0 &Z_{col}\\:
0 & 0 &N_{ped}&N_{col}\\
0 & 0 & 0 & 0\\:
0 & 0 & 0 & 0\\
0 &C_{lon}& 0 & 0\\:
D_{lat}& 0 & 0 & 0\\
\end{MAT}
\right]
\left[
\begin{MAT}(@){c}
\delta_{lat}\\
\delta_{lon}\\
\delta_{ped}\\
\delta_{col}\\
\end{MAT}
\right]
但是整个矩阵太大了
有没有办法将这个矩阵"缩小"或是转个90度让它变横的
谢谢
