The immediate problem can be solved with an array
, with a local setting of arraystretch
for reducing the gap between the two rows.
documentclass{article}
usepackage{amsmath,bm}
% old fashioned notation for the old fashioned supervisor
newcommand{vect}[1]{underline{#1}}
newcommand{matr}[1]{underline{underline{#1}}}
% better for typesetting
%newcommand{vect}[1]{mathbf{#1}} % or bm
%newcommand{matr}[1]{mathbf{#1}} % or bm
begin{document}
Here $vect{Q}$ and $vect{w}$ are column vectors and $matr{A}$ is a matrix
[
renewcommand{arraystretch}{0.7}
begin{array}{@{} c @{} c @{} c @{;} c @{}}
vect{Q} & {}={} & matr{A} & vect{w} \
scriptscriptstyle mtimes 1 &&
scriptscriptstyle mtimes n &
scriptscriptstyle ntimes 1
end{array}
]
end{document}
I strongly advise to use macros for inputting matrices and vectors. When your supervisor will realize that the old-fashioned notation is also very ugly in print (it was used in the typewriter times), you can simply change the definitions. If you switch the comments in the code above, the result will be
without changing the code in the document body.

@sanach - If your supervisor is so strongly wedded to this borderline unsuitable typographic convention, just show him the output ofunderline{Q}=underline{underline{A}},underline{w}
and ask him for permission to use a different, non-disastrous notation for vectors and matrices. :-)

The following screenshot shows five possibilities; I have no doubt that there are many more. Echoing a thought already expressed by David Carlisle, "blackboard-style" notational conventions (e.g., with one or two underlines) are not necessarily the best when applied to typeset, as opposed to hand-written, material.
