enter image description here



The above fraction is what I would like to achieve



What I have so far is



$ begin{bmatrix}
0 \
0 \
1 \
1
end{bmatrix} - frac{ begin{bmatrix}
0 & 0 & 1 & 1
end{bmatrix} begin{bmatrix}
1 \
1 \
1 \
1
end{bmatrix}}{begin{bmatrix}
1 & 1 & 1 & 1
end{bmatrix} begin{bmatrix}
1 \
1 \
1 \
1
end{bmatrix} }$


and it looks like this



enter image description here



How can I achieve my desired result?

    You also get several errors from that input.

  • The second $ causes TeX to leave math mode before your equation is finished. You should put it all the way at the end (after end{bmatrix} }). You may want to instead use [...] or begin{equation}...end{equation}instead of $...$ since this looks like a display equation rather than an inline equation.

    The fixed code compiles normally and has the expected result for me.

You could use the bsmallmatrix environment, provided by the mathtools package, to render the row and column vectors in the frac expression more compactly.



enter image description here



documentclass{article}
usepackage{mathtools}
begin{document}
[
begin{bmatrix}
0 \ 0 \ 1 \ 1
end{bmatrix}
- frac{
begin{bsmallmatrix}
0 & 0 & 1 & 1
end{bsmallmatrix}
begin{bsmallmatrix}
1 \ 1 \ 1 \ 1
end{bsmallmatrix}}{%
begin{bsmallmatrix}
1 & 1 & 1 & 1
end{bsmallmatrix}
begin{bsmallmatrix}
1 \ 1 \ 1 \ 1
end{bsmallmatrix} }
begin{bmatrix}
1 \ 1 \ 1 \ 1
end{bmatrix}
]
end{document}

    The smaller size of Frac is also possible, with a small redefinition:

    usepackage{tabstackengine}
    stackMath
    newcommandFrac[2]{{%
    setstackgap{L}{.7normalbaselineskip}TABstackMathstyle{scriptstyle}%
