\begin{equation}Y{(1)}=\left[\begin{array}{ccc}y{11} & y{12} & y{13} \y{21} & y{22} & y{23} \\vdots ...

\begin{equation}Y{(1)}=\left[\begin{array}{ccc}
y{11} & y{12} & y{13} \
y{21} & y{22} & y{23} \
\vdots & \vdots & \vdots \
y{a1} & y{a2} & y{a3}
\end{array}\right]\end{equation}

\begin{equation}Y{(2)}=\left[\begin{array}{ccc}
y{11} & y{12} & y{13} \
y{21} & y{22} & y{23} \
\vdots & \vdots & \vdots \
y{b1} & y{b2} & y{b3}
\end{array}\right]\end{equation}

\begin{equation}Y{(3)}=\left[\begin{array}{ccc}
y{11} & y{12} & y{13} \
y{21} & y{22} & y{23} \
\vdots & \vdots & \vdots \
y{c1} & y{c2} & y{c3}
\end{array}\right]\end{equation}
n=a+b+c

\begin{equation}X=\left[\begin{array}{cccc}
x{11} & x{12} & x{13} & x{14} \
x{21} & x{22} & x{23} & x{24} \
\vdots & \vdots & \vdots & \vdots \
x{n 1} & x{n 2} & x{n 3} & x{n 4}
\end{array}\right]\end{equation}

```tex \documentclass{article} \usepackage[a4paper]{geometry} \usepackage{mathtools} \begin{document} \begin{equation} Y_{(1)} = \begin{bmatrix} y_{11} & y_{12} & y_{13} \\ y_{21} & y_{22} & y_{23} \\ \vdots & \vdots & \vdots \\ y_{a1} & y_{a2} & y_{a3} \end{bmatrix} \quad Y_{(2)} = \begin{bmatrix} y_{11} & y_{12} & y_{13} \\ y_{21} & y_{22} & y_{23} \\ \vdots & \vdots & \vdots \\ y_{b1} & y_{b2} & y_{b3} \end{bmatrix} \quad Y_{(3)} = \begin{bmatrix} y_{11} & y_{12} & y_{13} \\ y_{21} & y_{22} & y_{23} \\ \vdots & \vdots & \vdots \\ y_{c1} & y_{c2} & y_{c3} \end{bmatrix} \end{equation} \[ n=a+b+cn=a+b+c \] \begin{equation} X = \begin{bmatrix} x_{11} & x_{12} & x_{13} & x_{14} \\ x_{21} & x_{22} & x_{23} & x_{24} \\ \vdots & \vdots & \vdots & \vdots \\ x_{n1} & x_{n2} & x_{n3} & x_{n4} \end{bmatrix} \end{equation} \end{document} ```
