Do you remember how to use the Fancy() function? I only found this http://www.mathworks.com/matlabcentral/newsreader/view_thread/12223
I would like to show in a fancy format all the outputs in the command line I get this error
>> fancy(x^2)
??? Undefined function or variable 'x'.
What do I need to install?

The FANCY function on the MATLAB newsgroup is not part of standard MATLAB. To make use of that code you need to copy it from the discussion in a new MATLAB file and save it in the MATLAB path.
If you are working with symbolic objects (that need Symbolic Math Toolbox) you can use the PRETTY command that is directly available with the toolbox.
A = sym(pascal(2))
B = eig(A)
pretty(B)

Please clarify as to which link did not work.
The newsgroup discussion includes the complete source for fancy() in it, but fancy() is for setting via LaTex using a particular Windows LaTex implementation. The pretty() command is built in to MuPad, but that requires that you have the Symbolic Toolbox. If your version of Matlab is old enough that you are using Maple as the symbolic engine, I am not certain that pretty() was available; pretty() is not part of the Maple language.

That *is* the newsgroup discussion link, and the source for fancy() is message #4 of 4 in the series.
