Hi,
Although I have chosen the short format in the code and command window display preferences. The results after using a "solve" command are displayed as:
y =
7770/23 - (32083660183526053*R)/12947848928690176000
Can anybody help me so that I can view the numerical values in short format? Like:
y = 337.83 - 0.0024779*R
Thanks

>> x=3^4/(2^3+2-4.5);
>> x=14.7273 -looks ok but not short.
>> vpa(x)
ans =
14.727272727272727272727272727273 -is not short at all LOL

By default vpa() pays attention to the current digits() setting, which defaults to 32. You can specify how many digits you want at the time of the vpa() call. For example,
>> vpa(x,5)
ans =
14.727
