You are quite right!

I had actually tried this, but i had posted the code twice in my preamble ^^

Thanks for the help

I have inserted alot of comments in my LyX file, now I need to be able to control if they are preinted or not. In my preamle I have put:

\RequirePackage{colortbl, tabularx}
\@ifundefined{comment}{}% do nothing if the comment environment is not defined
{% redefine the comment environment if it is ...

I recently read a paper wherein the listings each had a small header Like "Listing 14: EstOptions.m". Can anyone help me obtaining something similar in my LyX output ?

I need to write a proof of a theorem, and in my proof i have three asumptions i need to check (i, ii and iii). These are just 3 equations. What i am looking for is something that looks like this

Is there a nice way of doing this in the article class ?

Thank you

I have used LaTeX for years and LyX for the last 6 months, and now i need to do a presentaiton and have decided to continue with LyX using Beamer. But while there are plenty of layouts around, i havent been able to find a good tutorial

Does anyone have one ? (book, video, paper)

Thanks Frits, exactly what i needed


i modified your code slightly to force vectors to be lower case as well.

I am writting alot about statistics, and thereofre also Matrices and Vectors. To get a consistent way of using my notation i want to make some commands i could simply write before and after the expressions which are vectors or Matrices.

rules:
-Matrices and Vectors are both in bold
-Matrices are ...

I ended up rewritting the equation has two products instead and then using the "split" solution
