Thread Subject: Numerical representation

Hi,

Is there any command that let me change numerical number into a more readable form?

For example, instead of displaying

a =

0.833 -0.833

I want


a =

1/12 -1/12


I have seem Matlab sometimes return answer in like sin(2*pi), and sometimes like 23423423/42304923423. The latter is obviously a less desirable.

Any suggestion will be appreciated.

Symbolic toolbox can do it. But in that case values will be
sym objects rather than double matrices. Try:
sym(1/12)
double(23423423/42304923423)

thanks!
