I am writing a paper in JESTCH journal having document class \documentclass[a4paper,fleqn]{cas-dc}. I need to type a big matrix in a two column page. While I tried to type the whole matrix, I am facing the issue of overlapping of the matrix in two column page and the image is attached below.
I want to get my matrix without overlapping has same as the table format which fits in 1 column given below,
Can anyone help me to sort out this problem. Here I am attaching the matrix latex code
\documentclass[a4paper,fleqn]{cas-dc}
\begin{document}
$$K=\left[\begin{matrix}
1+{{x}^{4}}+{{x}^{6}} & x+{{x}^{4}}+{{x}^{6}}+{{x}^{7}} & 1+{{x}^{3}}+{{x}^{7}} & 1+x+{{x}^{2}}+{{x}^{3}}+{{x}^{5}} \
1+{{x}^{3}}+{{x}^{4}}+{{x}^{5}}+{{x}^{7}} & x+{{x}^{2}}+{{x}^{4}}+{{x}^{5}}+{{x}^{6}}+{{x}^{7}} & {{x}^{3}}+{{x}^{5}}+{{x}^{7}} & {{x}^{3}}+{{x}^{6}} \
x+{{x}^{2}}+{{x}^{4}}+{{x}^{5}}+{{x}^{6}}+{{x}^{7}} & 1+{{x}^{4}}+{{x}^{6}} & 1+x+{{x}^{2}}+{{x}^{4}}+{{x}^{5}}+{{x}^{6}}+{{x}^{7}} & {{x}^{4}}+{{x}^{5}}+{{x}^{7}} \
{{x}^{3}}+{{x}^{5}}+{{x}^{6}} & 1+x+{{x}^{2}}+{{x}^{7}} & {{x}^{2}}+{{x}^{3}}+{{x}^{4}}+{{x}^{5}}+{{x}^{7}} & x+{{x}^{2}}+{{x}^{3}}+{{x}^{5}}+{{x}^{7}}\
\end{matrix} \right]$$
\end{document}


stripenvironment, ftom thecutedpackage (sttoolsbundle). – Bernard Jun 30 '22 at 11:35stripenvironment. It works, but I felt some difficulty. When I used more than onestripenvironments frequently, I lost some sentences in between thestripenvironments. Could you please assist me to fix the problem. Thanking you in advance. – user273629 Jul 02 '22 at 10:08
