Loading the nicematrix package, the code

\begin{bNiceMatrix}[last-col,nullify-dots, margin]
    & & & \\
    \Cdots & A_j & \Cdots & i\\
    & & &
\end{bNiceMatrix}

generates this:

Can I get the dotted lines to be replaced with solid lines to get something analogous to the following?

  • Is there some documentation where I can read these techniques?

  • Another question: I guess this will affect the line-style globally. How can I restore that to default settings?

    The customization of the dotted lines (created by \Cdots, etc.) is documented in the page 27 of the official documentation of nicematrix (file nicematrix.pdf available for example on CTAN). You can use the key xdots (with its subkey line-style) locally for an environment or for a single command \Cdots.

  • Can one also have a mix of dotted and dashed lines as my desired output shows? I don't think it is possible by the option you suggest (though it fulfils the current requirement).
