Some old text books use single thick vertical lines for writing norms of vectors. I would like to define a pair of delimiters which behaves like \lvert
and \rvert
, but with thicker lines. The new delimiters should of course adapt to the size of the formula, just like \lvert
and \rvert
do. Can this be done?

Best Answer
There is an extensible delimiter called
\bracevert
, but it needs some coaxing:See the documentation of
mathtools
for\DeclarePairedDelimiter
, with respect to the syntax; our\oldnorm
command works the same.A more complex solution which also takes care of the spacing; the example also compares it with the standard
\Vert
symbols.
