I have a matrix composed of a real and imaginary part but it is too big to fit in the line and overflows. 
What is the best way to reduce its size?

 \[W^*_{642}=\left[ \begin{array} {cccc}
\ 1.5372\  & 1.4499\  & -0.8958\  & 1.3592\  \\ 
\ -0.1472\  & 1.0482\  & 1.8678\  & -0.4285\  \\ 
-0.0520\  & 0.8299\mathrm{\ \ } & 1.3499\mathrm{\ \ } & -0.2669\  \\ 
0.8216\  & \ 0.8565\  & -0.3562\  & 0.7059\  \end{array} 
 \right]
+ i\left[ \begin{array}{cccc}
\mathrm{\ \ -}\mathrm{0.7905} & \ 0.0101 & \ -\ 0.1503 & \ 1.4715 \\ 
\mathrm{\ \ }\mathrm{0.3275} & \ -\ 0.5116 & \mathrm{\ \ }\mathrm{0.7519} & \ -\ 0.6568 \\ 
\mathrm{\ -}\mathrm{0.1427} & \mathrm{\ \ }\mathrm{0.4836}\  & \ -\ 0.6818\  & \mathrm{\ \ }\mathrm{0.3105} \\ 
\ 0.4507 & \mathrm{\ \ \ }\mathrm{0.8530} & \ -\ 1.0814 & \ -\ 0.7589 \end{array} 
 \right]\] 


I tried using \scalemath{0.75}  and it does work though I needed to use it twice. Maybe you wizards have an easier method

 \[W^*_{642}=\left[\scalemath{0.75}  {  \begin{array} {cccc}
\ 1.5372\  & 1.4499\  & -0.8958\  & 1.3592\  \\ 
\ -0.1472\  & 1.0482\  & 1.8678\  & -0.4285\  \\ 
-0.0520\  & 0.8299\mathrm{\ \ } & 1.3499\mathrm{\ \ } & -0.2669\  \\ 
0.8216\  & \ 0.8565\  & -0.3562\  & 0.7059\  \end{array} }
 \right]
+ i\left[ \scalemath{0.75} { \begin{array}{cccc}
\mathrm{\ \ -}\mathrm{0.7905} & \ 0.0101 & \ -\ 0.1503 & \ 1.4715 \\ 
\mathrm{\ \ }\mathrm{0.3275} & \ -\ 0.5116 & \mathrm{\ \ }\mathrm{0.7519} & \ -\ 0.6568 \\ 
\mathrm{\ -}\mathrm{0.1427} & \mathrm{\ \ }\mathrm{0.4836}\  & \ -\ 0.6818\  & \mathrm{\ \ }\mathrm{0.3105} \\ 
\ 0.4507 & \mathrm{\ \ \ }\mathrm{0.8530} & \ -\ 1.0814 & \ -\ 0.7589 \end{array} }
 \right]\] 

Thank you

If you find yourself adding extra spaces like that, it's always the wrong thing. 
Never use "\  " to try and force formatting — LaTeX has proper ways to do this which are much easier

\documentclass{article}
\usepackage{dcolumn}
\newcolumntype{d}{D{.}{.}{4}}
\arraycolsep.5ex
\begin{document}
{\footnotesize
  \[W^*_{642}=\left[\begin{array} {dddd}
      1.5372&1.4499&-0.8958&1.3592\\
      -0.1472&1.0482&1.8678&-0.4285\\
      -0.0520&0.8299&1.3499&-0.2669\\
      0.8216&0.8565&-0.3562&0.7059\end{array}
      \right]
  + i
  \left[\begin{array}{dddd}
      -0.7905&0.0101&0.1503&1.4715\\
      0.3275&0.5116&0.7519&-0.6568\\
      -0.1427&0.4836&-0.6818&0.3105\\

}

In new version of pdfLaTeX appeared strange bug. If I use command

pdflatex a.English.tex

I cannot finish compilation because it terminates without any specific error message. If I change command

pdflatex a.English.tex >a.txt

then compilation is successful. Any ideas what I can do to see process on console like I did before

We need more help from you to answer this:

1. What distribution? (TeX Live, MiKTeX, MacTeX, etc)

2. What version of pdflatex?

3. What version of LaTeX?

4. What is the last message you see before it terminates?

5. Create a minimal example (remove everything unnecessary from the file
until you get the smallest file which shows the error)

6. If you are using Windows, I think there is a problem using filenames
with more than one dot. Rename a.English.tex to a-English.tex and try that.

1. I use MiKTeX 20.6 and made today fresh update

 

2. I use pdflatex, but in the log file I see pdfTeX, Version 3.14159265-2.6-1.40.21

 

3. This is amsbook class

 

4. What is the last message you see before it terminates?

Last text in log file is

] [10] <xymatrix 3x2 141>

 

Overfull \hbox (1.47255pt too wide) in paragraph at lines 714--717

[][][]\T2B/cmr/m/sc/10 Теорема \T2B/cmr/m/n/10 2.2.6\T2B/cmr/m/sc/10 . []\T2B/c

mr/m/it/10 Про-из-ве-де-ние су-.

 

I think there is problem to output text to console. When I order text to file, compilation goes to finish.  

 

5. Create a minimal example (remove everything unnecessary from the file

until you get the smallest file which shows the error)

 

I expected this request. However I am not sure this is real task. Even compilation terminates on page 8, this is about 10 files

 

6. If you are using Windows, I think there is a problem using filenames

with more than one dot. Rename a.English.tex to a-English.tex and try that.

 

I work with such packages more than 15 years.

I've never heard of that happening before. But that Cyrillic might
possibly be triggering some weird behaviour from the console if the
encoding is being misinterpreted as control characters.

The next choice is a binary split. Find the file in which the error
occurs, and insert /end{document} in the middle of it (50% through).
Process it.

If there is no error, move the \end{document} to the 75% mark. Repeat.

Keep moving the \end{document} until the error occurs, then move it back
until the error does not occur, and then you have found the line.

OK, so that's not it.

But as it works fine in TL 2017, I suspect it is using some macro that
has been changed in more recent versions.

I do not think it relates directly to Cyrillic. I compile two version, one using Cyrillic and another plain English. It happened today after update. May be they will fix it in next version. I just let know that this happened. I think it relates to amount of output to console, may be number of buffers in output file.

I have one more question related to this problem. PdfLaTeX has option -quiet which should reduce amount of output to console. If it would work properly, then it could reduce time of compilation. This make sense when I compile text 200 - 300 pages long. But this option never worked as I expected. Is there way to reduce output to console and see only error messages?

Thank you

Given who wrote TeX, I doubt it.

Pipe stderr through a filter for error messages?

I checked option to use pre-released packages. And everything works fine.

 

I did not understand your second question. What I wanted to do is to reduce output to console during translation, but I am not sure if this is possible.

 

Thank you,

Sorry, I was not very explicit.

I meant

$ pdflatex a.English.tex 2|grep -A2 '^\!'

That just shows the errors, nothing else. But that only works on Mac,
Linux, and Windows/cygwin as far as I know. There may be a way to pipe
std.err in Windows but I don't know how to.

Yes, you write this is explicitly lunix format. I will think about this, thank you.
