  • How much sense does an array inside a matrix make?

it is simple to lost in your code fragment. i try to clean up only first three row, other i left to you that you clean-up others rows on the similar way as i do in the first three rows...

\documentclass{article}
\usepackage{nccmath}
\usepackage{makecell}

\begin{document}
    \[\setcellgapes{3pt}
      \makegapedcells
\begin{pmatrix}
 x + \cosh[2t]   & 0 & \mfrac{-3x + \sinh[2t]}{\sqrt{2}}  & 0
    & - \mfrac{x + \sinh[2t]}{\sqrt{2}} & 0      \\
0 & x + \cosh[2] & 0 & - \mfrac{- 3x + \sinh[2t]}{\sqrt{2}}  & 0
    & \mfrac{x + \sinh[2t]}{\sqrt{2}}            \\
0 & x + \cosh[2] & 0 & - \mfrac{-3x + \sinh[2t]}{\sqrt{2}}  & 0
    & \mfrac{x + \sinh[2t]}{\sqrt{2}} 
\end{pmatrix}
    \]
\end{document}

edit:

  • package nccmath is used for medium size fractions (\mfrac) in the matrix
  • package makecell is used for (unusual) determining vertical space between matrix rows
  • note, the matrix is very wide, so it can happen that it will not be within text width. if this is a case, it might help to use math environment mmatrix, i.e.:

    \left(\begin{mmatrix}  % <--- observe double m
    <content of matrix>
          \end{mmatrix}\right)

First of all to better show the whole matrix in your pdf sheet, I set the side margins to 1in with the geometry package:

\usepackage[margin=1in]{geometry}

After I have used the nicematrix package with the same strategy as on page 13 of the manual and of which I also enclose a screenshot.

The MWE output is:

\documentclass[a4paper,12pt]{article}
\usepackage[margin=1in]{geometry}
\usepackage{amssymb}
\usepackage{nicematrix}
\begin{document}
\[\begin{pNiceMatrix}
x + \cosh[2t] & 0 & \dfrac{-3x + \sinh[2t]}{\sqrt{2}} & 0
    &-\dfrac{x + \sinh[2t]}{\sqrt{2}} & 0\\
    \noalign{\kern.5mm}
0 & x + \cosh[2] & 0 & -\dfrac{- 3x + \sinh[2t]}{\sqrt{2}} & 0
    & \dfrac{x + \sinh[2t]}{\sqrt{2}}\\
    \noalign{\kern.5mm}
0 & x + \cosh[2] & 0 & -\dfrac{-3x + \sinh[2t]}{\sqrt{2}} & 0
    & \dfrac{x + \sinh[2t]}{\sqrt{2}} 
\end{pNiceMatrix}\]
\end{document}

You have a very bulky matrix with repeating entries. So you may typeset it as

\documentclass[fleqn]{article}
\usepackage{amsmath}
\begin{document}
 \[
    \begin{pmatrix}
        a&0&b&0&-e&0\\
        0&a&0&b&0&e\\
        b&0&c&0&d&0\\
        0&b&0&c&0&d\\
        -e&0&d&0&f&0\\
        0&e&0&d&0&f
    \end{pmatrix}
    \]
where
\begin{align*}
a&=x + \cosh \left[ {2t} \right]\;, &
b&=\frac{{ - 3x + \sinh \left[ {2t} \right]}}{{\sqrt 2 }}\;,\\
c&=\frac{1}{2}\left( {1 + 9x + \cosh \left[ {2t} \right]} \right)\;, &
d&=\frac{1}{2}\left( {1 + 3x - \cosh \left[ {2t} \right]} \right)\;,\\
e&=  \frac{{x + \sinh \left[ {2t} \right]}}{{\sqrt 2 }}\;,&
f&=\frac{1}{2}\left( {1 + x + \cosh \left[ {2t} \right]} \right)\;.
\end{align*}    
\end{document}

This solves the problem and makes the readers a bit happier. Of course, you could write it as block matrix of 2x2 matrices to further improve the presentation,

\documentclass[fleqn]{article}
\usepackage{amsmath}
\DeclareMathOperator{\diag}{diag}
\begin{document}
 \[
    \begin{pmatrix}
     A & B & E\\
     B & C & D \\
     E & D & F \\
    \end{pmatrix}
\]
where $A=\diag(a,a)$, $B=\diag(b,b)$, $C=\diag(c,c)$, $D=\diag(d,d)$,
$E=\diag(e,-e)$ and $F=\diag(f,f)$ with
\begin{align*}
a&=x + \cosh \left[ {2t} \right]\;, &
b&=\frac{{ - 3x + \sinh \left[ {2t} \right]}}{{\sqrt 2 }}\;,\\
c&=\frac{1}{2}\left( {1 + 9x + \cosh \left[ {2t} \right]} \right)\;, &
d&=\frac{1}{2}\left( {1 + 3x - \cosh \left[ {2t} \right]} \right)\;,\\
e&=  \frac{{x + \sinh \left[ {2t} \right]}}{{\sqrt 2 }}\;,&
f&=\frac{1}{2}\left( {1 + x + \cosh \left[ {2t} \right]} \right)\;.
\end{align*}    
\end{document}

  • It may be better to say $A=(x+cosh[2t])I_2$, etc. And maybe $E=diag(1,-1)(x+sinh[2t])/\sqrt2$.
