我正在尝试运行此代码，但没有结果。请帮忙。可能需要合适的包，但我没有得到。请帮忙。输出应该是这样的：
答案1
代替
\usepackage{filecontents,amsfonts,amsmath,amssymb,blkarray,multirow,graphics,amsthm,varioref,mathrsfs,amscd,amsopn,epsfig,fancyhdr,latexsym,makeidx,enumerate,titlesec,supertabular}
经过
\usepackage{pstricks}
因此pstricks已加载（这里不需要其他任何包，也不epsfig应该使用它们，它用于模拟 20 世纪 80 年代的 LaTeX2.09 文档）
然后运行latex（不是 pdflatex），dvips生成ps2pdf -dALLOWPSTRANSPARENCY的文档是
答案2
