There was a similar question asked some time back. The solutions was to use the package amsmath
and define norm
as
\newcommand{\norm}[1]{\left\lVert#1\right\rVert}
However, I am using the packages newpxtext
and newpxmath
and it is advised not to amsmath with them. How can I then achieve a re-scaled norm sign in LaTeX?
amsmath
? I suppose you meanamsfonts
oramssymb
?amsmath
is loaded bynewpxmath
, but following the advice on the linked page, if i define thenorm
as\newcommand{\norm}[1]{\left\lVert#1\right\rVert}
, I get the error that it is already defined
