第一个是文本的“Literaturnaya”字体和数学的 Computer Modern 字体的混合:
\documentclass[a4paper]{article}
\usepackage{literat}
\DeclareSymbolFont{operators}{OT1}{\familydefault}{m}{n}
\addtolength{\textwidth}{-2.2cm} % to emulate the original
\begin{document}
Here $v^+$ is the pseudoinverse matrix for the column matrix $v$.
From verification of Moore-Penrose conditions it can be readily
seen that
\[
v^+=\frac{1}{\delta}v^{\mathrm{T}}
\]
where the number $\delta=u_1^2+u_2^2+\ldots+u_n^2$.
Here, $v^{\mathrm{T}}=(v_1v_2\ldots v_n)$ -- the row composed
of the elements of column~$v$. Consequently, the estimate
$\widehat{b}$ by the LSM for coefficient~$b$ is found as
\[
\widehat{b}=\frac{u_1v_1+u_2v_2+\ldots+u_nv_n}{\delta}=r'\chi,
\]
\end{document}
(我修正了几个错别字。)
以下是页眉的复制版
Literaturnaya 字体可以通过以下方式安装getnonfreefonts
(参见http://tug.org/fonts/getnonfreefonts)
我认为其他两本书无法用现有字体重现。坦白地说,我认为第三个例子(以及所有旧 MIR 书籍)的排版非常糟糕。
