format short, format compact
may suit.
If not, see format as to the options at comand line for echo'ed output.
If you want/need a specific output, then you'll have to format/write it yourself.
Show us code/and what you're getting that you don't like; we can't see your terminal from here...

If you are using the Symbolic Math Toolbox, use the double function if the expressions do not contain symbolic variables. If they do contain symbolic variables, numeric values must be supplied for them first, using the subs function. (The vpa function will also provide strictly numeric results, however the result will still be a symbolic variable.)

sympref('FloatingPointOutput',true);
I personally do not recommend this approach, as I find that there are many cases where the symbolic form is more informative.
