Hello,

I'd like to achieve the attached image in LaTeX.

How could I make a rectangle around a bunch of cells in LaTeX?

Thanks

Do you know the karnaugh package on CTAN?

I used it long time ago. More recently, but still some years ago I made some Karnaugh maps with TikZ. If you are interested I can send you some example.

Yes but it doesnt arrange the K maps as I want them to do (ie. not in the correct standard cell order).

Therefore I would like to do it myself..

I've found my tikz code for Karnaugh maps. Command names are in catalan, but I've added some comments in English. I hope you could understand them. You only need tikz. Next you'll find the code with two examples using it.

Best regards,

Ignasi

Hello,

I am having the same issue. Did you find the right code?

Were you able to draw the kmap in your picture?

Thank you
OOzy

Have you tested the code I posted in my previous answer?

Hello,

Yes, I did but it does not produce the image shown above with:

Code: Select all

    
    A
________

I hope you get it.

Thank you

I think that the line which marks negate or not negate variables is not necessary if you uses 0 and 1 to label rows and columns, but, in any case, I've made some changes to the code and something similar to wanted lines and labels are shown now.

I hope you could adapt the code to your needs.

I improved a little the code that I copied here (now you can draw maps up to 3x3 variables) and put it inside this .sty file, to use like a package. Feel free to use it.
