Math & Science ⇒ Handling a too big matrix equation

[arastpour]

I was wondering if I could rotate the equation below to fit it on a page without compromising the font size.

I tried landscape and rotating packages to rotate the equation. In both cases I received error messages!

What error messages do you get? That is some important information.
Have a look at the following, even with font size tiny it doesn't fit the page.

A Minimal Working Example would be helpful for future questions. For example, I don't knnow which documentclass you are using.

Hi Johannes_B,

I do appreciate your time and feedback.

Would you please take a look at the file that I have attached (Untitledq.png). It is a screen shot of my out put when I copied and pasted your code. The same thing happens with other solutions that I have found for my problem--the matrix sticks out of the screen!
Best,
Amir

on my machine it just is flushed down on the left side (bottom of portait), i attached the pdf.
You can also click on Open in writelatex to see the same output.

Do not look at the DVI version of the document. Always look at the PS or PDF output. Most DVI viewers can't display objects that are rotated this way.


Best regards and welcome to the board
