Ich hab hier was
\(\begin{equation*}
\left| \begin{aligned}
\,&n =\operatorname{rows} \left( A \right) \\
\,&L = \operatorname{matrix} \left( n \,;\, n \right) \\
\,&\begin{split}& \operatorname{for} \:\, j \in {1} \textbf{\,.\,.\,} {\left( n-1 \right)}\\& \quad
\left| \begin{aligned}
\,&{L}_{\,j\,j\,} = \sqrt{{A}_{\,j\,j\,}-\sum_{k = 1}^{j} {\left( {L}_{\,j\,k\,} \right)^{2}}} \\
\,&\begin{split}& \operatorname{for} \:\, i \in {\left( j+1 \right)} \textbf{\,.\,.\,} {n}\\& \quad
\left| \begin{aligned}
\,&{L}_{\,i\,j\,} =\left( {A}_{\,i\,j\,}-\sum_{k = 1}^{j} {\left( {L}_{\,j\,k\,} \cdot {L}_{\,i\,k\,} \right)} \right) \cdot \frac{1}{{L}_{\,j\,j\,}}\end{aligned} \right.\\\end{split}\end{aligned} \right.\\\end{split} \\
\,&{L}_{\,n\,n\,} = \sqrt{{A}_{\,n\,n\,}-\sum_{k = 1}^{n-1} {\left( {L}_{\,n\,k\,} \right)^{2}}}\end{aligned} \right.
\end{equation*} \)
was gar nicht gerendert wird. Das Bild dazu

woran liegts?
