Math & Science ⇒ Symbol for »not proportional to«

[juliette]

Hello, I couldn't find a "not proportional to symbol" .. I just want \propto but with a line through it.

I haven't figured out how to use MetaFont to create my own symbols yet, so if the character already exists I'd be eager to know!

Hi,

perhaps something like this?

Code: Select all

\documentclass[11pt]{article}
\usepackage{cancel}

\begin{document}

$\cancel{\propto}$

\end{document}

This was the best I could do, but it still doesn't look so nice:

Code: Select all

\makeatletter
\newcommand{\notprop}{\propto\kern-1\@ptsize pt \diagup}
\makeatother

If anyone has a better solution, I'd be eager to learn it!

\not\propto might produce an acceptable result.

Oh thanks gmedina! I didn't see your post before I posted again.
That's neat, I didn't know about \cancel,

I think I like the solution that I posted afterwards a little bit more because not as much of the \propto gets hidden, but I would still either like to have the \propto a little bit bigger so that the top arm doesn't get covered by the slash, or I would like to have the slight pointing at less of an angle with respect to the vertical... maybe I'm asking for too much.

\not\propto is a lot nicer, thanks phi and gmedina!
