数学公式

$$\hat{\theta}$$

$$\prod \limits_{i=1} \limits^{n} p(x_i;\theta)$$

• $$\begin{equation} \left\{ \begin{aligned} x(t) &=A_{ci}x(t)+B_{1ci}w(t)+B_{2ci}u(t) \\ z(t) &=C_{ci}x(t)+D_{ci}u(t) \\ \end{aligned} \right. \end{equation}$$

  ​

$$\left. \frac{\partial L}{\partial X} \right| _{X=X^*} =0$$

$$\begin{equation} \left\{ \begin{aligned} \left. \frac{\partial L}{\partial X} \right| _{X=X^*} =0 \hspace{10mm} (1)\\ \lambda i \neq 0\hspace{10mm} (2) \\ \mu_k \geqslant 0 \hspace{10mm} (3) \\ \mu_k g_k (X^*) >= 0 \hspace{10mm} (4) \\ h_j(X^*) = 0,j=1,2,\cdots,p \hspace{10mm} (5) \\ g_k(X^*) = 0,k=1,2,\cdots,q \hspace{10mm} (6) \end{aligned} \right. \end{equation}$$

$$\operatorname*{arg min}_{\omega,b} f(x)$$

$$\begin{bmatrix} \frac{5}{6} & \frac{1}{6} & 0 \\[0.3em] \frac{5}{6} & 0 & \frac{1}{6} \\[0.3em] 0 & \frac{5}{6} & \frac{1}{6} \end{bmatrix}$$

$$F(x) = \int_{-\infin}^{x} f(t) \mathrm{d}t$$
