I have used \begin{bmatrix} and \setcounter{MaxMatrixCols}{20} to get this matrix . how do i assign it in center or scale this matrix .....?

I would do something like the following (with no attempt for aesthetics)
\documentclass{article} \usepackage{amsmath,amsfonts} \begin{document} We did symmetric matrix stuff. Let $K_1, K_2, K_3, K_4$ be symmetric matrices defined as \[ \mathbb{J} = \begin{bmatrix}1&-1\\-1&1\end{bmatrix},\ K_2 = \begin{bmatrix} \frac{12EI}{L^2}&\frac{12EI}{L^2}&\frac{12EI}{L^2}&\frac{12EI}{L^2}\\ \star&\frac{12EI}{L^2}&\frac{12EI}{L^2}&\frac{12EI}{L^2}\\ \star&\star&\frac{12EI}{L^2}&\frac{12EI}{L^2}\\ \star&\star&\star&\frac{12EI}{L^2} \end{bmatrix},\ K_3 = \begin{bmatrix} \frac{12EI}{L^2}&\frac{12EI}{L^2}&\frac{12EI}{L^2}&\frac{12EI}{L^2}\\ \star&\frac{12EI}{L^2}&\frac{12EI}{L^2}&\frac{12EI}{L^2}\\ \star&\star&\frac{12EI}{L^2}&\frac{12EI}{L^2}\\ \star&\star&\star&\frac{12EI}{L^2} \end{bmatrix} \] then \[ K = \begin{bmatrix}\frac{EA}{L}\mathbb{J}&&&\\&K_2&&\\&&K_3&\\&&&\frac{JG}{L}\mathbb{J}\end{bmatrix} \] \end{document} 
- Thank You. I have another matrix which is even bigger than this,Can you help me with aligning matrix in Landscape mode ..?1450– 14502017-07-20 09:48:20 +00:00Commented Jul 20, 2017 at 9:48
Ka 4x4 matrix. It will still cover less space.
