Can I use variables on an IPython notebook markup cell?

Question

I have an IPython notebook and I would like to use one of my variables inside a markup cell. Is this even possible? If so, how do you do it?

Answer 1

If you don't mind a code cell that does the job, there is a possibility without adding any extensions.

from IPython.display import Markdown as md

fr=2 #GHz

md("$f_r = %i$ GHz"%(fr))

This will show a markdown cell in a nicely LaTeX formatted output
