# [Tex/LaTex] Making a thicker \cdot for dot product (that is thinner than \bullet)

math-modesymbols

I'm trying to replicate the dot that my professor uses in his notes for the dot product between vectors but I am having a hard time doing so. This is what it looks like:

I have tried a couple of things. \cdot is too thin

and \bullet is too thick

and using \Large with \cdot gives an error. Moreover, after digging through the list of symbols I cannot find a nice medium between \cdot and \bullet.

How can I get a dot closest to the first picture?

May be you find a better name like \dotp or something like that.

\documentclass{scrartcl}
\usepackage{graphicx}

\makeatletter
\newcommand*\bigcdot{\mathpalette\bigcdot@{.5}}
\newcommand*\bigcdot@[2]{\mathbin{\vcenter{\hbox{\scalebox{#2}{$\m@th#1\bullet$}}}}}
\makeatother

\begin{document}
$a \bigcdot b$
\end{document}
