disp() output in decimal form

I'm trying to display a table with the values I have stored in some vectors, but when I do it, it shows the results in fractions, and not in decimal form, even though I have tried

format short 

The code looks like

disp(['   x   ', '  y1  ', '  y2  ', '  yex  ', 'error1', 'error2'])
disp([xv',y1',y2',yex',error1',error2'])

Where xv, y1, y2, yex, error1 and error2 are row vectors that store the data I want to display (they've been transposed so they appear in columns).

The output looks like

      x          y1                            y2              yex              error1                                          error2
[     0,         1,                                  1,          1,                     0,                                              0]
[  1/40,       1/2,                                5/8,  exp(-1/2),       exp(-1/2) - 1/2,                                5/8 - exp(-1/2)]
[  1/20,       1/4,                              25/64,    exp(-1),         exp(-1) - 1/4,                                25/64 - exp(-1)]
[  3/40,       1/8,                            125/512,  exp(-3/2),       exp(-3/2) - 1/8,                            125/512 - exp(-3/2)]
    

But with more values in the columns, whose fractions start to grow bigger and bigger, like

95367431640625/1152921504606846976

Which makes it pretty annoying and inconvenient.

What could I do to fix this?

Thanks!

Use double() or vpa() it looks like the results are from symbolic calculations.

[madhan ravi]

disp(double([xv',y1',y2',yex',error1',error2']))

Thanks!

It really worked.

The results were coming from symbolic calculations indeed.

I didn't think of that.
