Something like:

\beta = [], \quad \beta = [], \quad \beta = [].

So that the three forms of beta fit on one line.

I want the \beta = to valign with the first element of the vector/matrix.

I want all the remaining betas to be in the same position.

I want the [] matrix/vectors to be all vertically aligned.

I want it to work within \begin{equation} environment, \begin{align} environment, \begin{array} environment, $math$, and/or \[ \]

Please see attached image, and thanks in advance!

UPDATE Verifying that solution provided by David Carlisle works with font size changes

\documentclass[10pt]{article}

\usepackage{delarray}

\DeclareMathSizes{10}{24}{14}{14}

\begin{document}
\[
\beta =
\begin{array}[t]\lbrack{c}\rbrack v_1\\ v_2 \\ v_3 \\ v_4 \end{array}
, \quad \beta =
\begin{array}[t]\lbrack{c}\rbrack v_1\\ v_2 \\ v_3 \\ v_4 \\ v_5 \\ v_6 \end{array}
, \quad \beta =
\begin{array}[t]\lbrack{c}\rbrack v_1\\ v_2 \\ v_3 \\ v_4 \\ v_5 \\ v_6 \\ v_7 \\ v_8 \\ v_9 \end{array}
.
\]
\end{document}

  • really, there should be a general question about how to use [t], [b], and [c] to align various objects. – barbara beeton Feb 8 '16 at 11:38
  • @barbarabeeton although here it is specific delarray package syntax, if you use \left[\begin{array}[t] you get something rather different. – David Carlisle Feb 8 '16 at 12:20
  • Yes, it doesn't work with the regular array environment, so I will probably have a collision in the final document (which uses the default array package) – mshaffer Feb 8 '16 at 17:05
  • @mshaffer No. delarray and (half of) array were written by the same person, and delarray uses array. They are as compatible as two packages can ever be. – David Carlisle Feb 8 '16 at 17:07
  • @david-carlisle Yes, generally you are correct, but the manuscript template prepared by a journal does have some sort of collision and only the betas = ., appear the [] and everything inside are gone. I will compile independently and include – mshaffer Feb 8 '16 at 17:20
