Solution:

              Fitness
              _______
    FitA1     10.089 
    FitA2     1.3061 
    FitA3     0.2248 
    FitA4     10.314

tblB =
  17×1 table
              Fitness
              _______
    FitA4     10.314 
    FitA8     10.286 
    FitA1     10.089 
    FitA7     9.6263 
    FitA11    9.5584 
    FitA5     9.4294 
    FitA6     9.4015 
    FitA9     9.2834 
    FitA10    9.2834 
    FitA12    9.2046 
    FitA2     1.3061 
    FitA13    0.8844 
    FitA15    0.8844 
    FitA3     0.2248 
    FitA16    0.2248 
    FitA14         0 
    FitA17         0
Now my problem….
I need to be able to work with each Fitness number and his procedence… for example, the higher Fitness number: 10.314, I need to assign him from wich group comes, in this case comes from 'FitA4'… so will need something like: FitA4=10.314. Like that with the rest numbers and RowNames…
I appriciate any help.

"...''FitA4'... will [become]: FitA4=10.314."
This is called dynamic variable naming and it's not a good strategy. You already have a very nice, tidy table so don't break it apart into separate variables. Use the table itself. The one line below shows how to get the Fitness value of FitA4 from the table. 
x = tblB.Fitness(ismember(tblB.Properties.RowNames, 'FitA4'))
Here's how to get several values 
x = tblB.Fitness(ismember(tblB.Properties.RowNames, {'FitA4','FitA2','FitA11'}))
