Math & Science ⇒ One column math formula in 2-column mode paper

[sd07501]

Dear all,
I am going to prepare a paper. However, I meet a problem of presenting very long math formula in 2-column mode the same as example in this attachment. Please, somebody tell me how. I greatly appriciate for your helps.

Hi there,

I have not tried anything that before, therefore this is just a way to get ideas rolling.

Did you try putting your long math equation into a minipage that would spread over the two column?

Did you try getting into a one column format just for the math environment?

Cheers

Hi sd07501,

Which document class are you using? Perhaps you could use the multicol package to switch between two and one-column mode.

Thanks for all replies.
@fatra2: I want to present my paper similar to the example in attached picture. I means It includes horizon line and long math, numbered equations.
@gmedina: I have tried muticol package with my current document class IEEEtran.cls, but it still doesn't work corectly. Gmedina, would you please post an intuitive example code for switching from 2-column to 1-column mode and vice versa. I greatly appreciate for your helps.

Best Regards

Since you are using the IEEEtran document class, you could include your equation using a figure* environment; the document How To Use the IEEEtran LaTeX class contains a detailed explanation on how to proceed and an example (See 1) Double Column Equations, page 11).

Code: Select all

\begin{figure*}
\hline
\begin{equation}

%write your equation here

\end{equation}
\end{figure*}

Code: Select all

\begin{figure*}
\hline
\begin{equation}

%write your equation here

\end{equation}
\end{figure*}

So? This is exactly what I suggested in my previous reply.

Hi all,

Thanks very much for intuitive examples. I tried and got the folowing error:
! Misplaced \noalign.
\hline ->\noalign
If I remove \hline, it works well and has no separate line. Can anybody help me!! Thanks very much.

We need to see your document, in order to (try to) help you! Well, at least I do.

Hi,

I didn't notice that error in shopaholiconline's code. Replace \hline with \hrule.
