Get rid of the two & tab separators...they result in the creation of a 2nd column in the matrix.



documentclass{article}
usepackage{amsmath}
begin{document}
begin{gather}
W =
begin{bmatrix}
{1^W}^T\
{2^W}^T \
. \
. \
{s^W}^T
end{bmatrix}
end{gather}
end{document}


enter image description here



Also, consider replacing the .\.\ with vdots\, as in



documentclass{article}
usepackage{amsmath}

    Why is there more space between {2^W}^T and vdots?
    – manooooh
    Dec 4 at 3:32






  • 5




    @manooooh -- vdots is constructed from periods, which sit on the baseline, so there's quite a lot of "air" above the top one. some methods for compacting them or adjusting the vertical space appear in answers to tex.stackexchange.com/q/412407/579 .

  • @barbarabeeton excellent! It is something similar with [begin{cases}...end{cases} equiv begin{cases}...end{cases}], right?
    – manooooh
    Dec 4 at 4:20

    @manooooh it is similar if you wish the syntax of cases (left brace, no right brace). Another differrence, bmatrix uses center alignment, where as cases uses right/left, right/left alignment.
