\renewcommand*{\emptyset}{\varnothing}  % prettier empty set symbol
\ifLM\newcommand*{\transp}{\mathsf{T}}\fi  % use for matrix transpose

%\usepackage{bm}  % use `\bm` for bold math symbols

% Use `\phanrel` to insert an invisible relation operator to align an equation split across two lines.
\newcommand*{\phanrel}{\mathrel{\phantom{=}}}
