MATLAB output is a bunch of numbers with operators not the exact number

Hi,

When i ask MATLAB to solve a problem using syms and det , in output section it showes as series on formulas that needed to be calulated and not the exact value. How can I ask matlab to show the exavt number and not numers with operators ? for example instead of (25/6 - (5*13^(1/2))/6)^(1/2) shows 1.078 in commant window

A =
 
  (25/6 - (5*13^(1/2))/6)^(1/2)
  ((5*13^(1/2))/6 + 25/6)^(1/2)
 -(25/6 - (5*13^(1/2))/6)^(1/2)
 -((5*13^(1/2))/6 + 25/6)^(1/2)

while it should be :

     1.0780
     2.6779
    -1.0780
    -2.6779

Thanks ... It worked

To be pedantic, those expressions are the exact result. The decimal values are an approximation.

That said, you should be able to use double() to convert the symbolic expressions to numeric.

Yes you're right, it just worked when I used double().. Thanks.
