if you want to display a matrix you can use disp(matrix)

To use disp and have two decimal points, use format bank first, otherwise will get whatever precision is associated with the current format. Have often thought there should be some ability in disp to have some control over formatting without the full need of fprintf and derived friends.
Otherwise, num2str
disp(num2str(x,'%.2f'))
or, for more control over where placed since disp trims leading blanks in the above
>> format short,format compact
>> disp(A)
240.1400 0.0032
5.0000 3.0000
3.1416 6.0000
6.0000 4.0000
8.0000 0.0000
>> fprintf('%10.2f%10.2f\n',A.')
240.14 0.00
5.00 3.00
3.14 6.00
6.00 4.00
8.00 0.00
>>
General form would be something like
fprintf(repmat('%10.2f',1,size(x,2)) '\n',x.')
