Double line over math character

Postby Bozack » Thu Oct 16, 2008 3:40 pm

Hi

I'm writing a report with a lot of matrices in it - most of the time shortened to simply being written as a single letter. But I'd like to be able to distinct them from other letters (vectors and simple letters with nothing over them) by having a double line over the letter corresponding to a matrix.

I've been looking everywhere, but simply can't figure out how to do this... Can anyone help? :)

Hi Bozack,

you could use \bar{\bar{...}} or perhaps \overline{\overline{...}}.

If you need such double accented symbols very often in your report, you can use the amsmath package to define these new symbols, optimize accent placement and expedite their output at the same time.
\accentedsymbol{\dbarA}{\Bar{\Bar{A}}
