Math & Science ⇒ Column Vector in Array too wide

[FliegenderZirkus]

Hello community,

I am trying to obtain a column vector with left aligned elements.

Code: Select all

\left\{\begin{array}{l}
x_{abc}\\
y_d
\end{array}\right\}

\begin{Bmatrix}
  x_{abc}\\
  y_d
\end{Bmatrix}

I would like to either

1. get rid of the white space in the {array} solution or
2. left align the Bmatrix solution.

Any ideas how to do any of the two?

Thanks!

In an {array} environment there is a separating space between columns that is determined by the length \arraycolsep (default value 5pt). This applies also to the position before the first column and after the last one (which is the same here). You can get rid of it by adding @{} at the corresponding positions in the {array} preamble to remove that gap.

Code: Select all

\left\{
\begin{array}{@{}l@{}}
  x_{abc}\\
  y_d
\end{array}
\right\}

For a solution with the matrix environment from amsmath see the blog entry »Matrices with alignment« by our administrator.

I see, both solutions offer just what I need, thank you. Next time I'll try to look for existing answers better!
