这是我 LaTeX 公式的源代码:
$\left\{\begin{array}{rrrr}f_{x i}^k \\ f_{y i}^k \\ f_{x j}^k \\ f_{y j}^k\end{array}\right\}=\frac{A*E}{L_k}\left[\begin{array}{rrrr}c_k^{2} & c_k s_k & -c_k^{2} & -c_k s_k \\ c_k s_k & s_k^{2} & -c_k s_k & -s_k^{2} \\ -c_k^{2} & -c_k s_k & c_k^{2} & c_k s_k \\ -c_k s_k & -s_k^{2} & c_k s_k & s_k^{2}\end{array}\right]\left\{\begin{array}{l}u_{i} \\ v_{i} \\ u_{j} \\ v_{j}\end{array}\right\}=\left[\begin{array}{rrrr}K^{k}_{11} & K^{k}_{12} & K^{k}_{13} & K^{k}_{14} \\ K^{k}_{21} & K^{k}_{22} & K^{k}_{23} & K^{k}_{24} \\ K^{k}_{31} & K^{k}_{32} & K^{k}_{33} & K^{k}_{34} \\ K^{k}_{41} & K^{k}_{42} & K^{k}_{43} & K^{k}_{44} \end{array}\right] \left\{\begin{array}{rrrr}u_{i} \\ v_{i} \\ u_{j} \\ v_{j}\end{array}\right\}$
