Hi Tobias,

My understanding is that you want to concatenate the double array to a struct/table and by "double array" you mean array having the double type values.

For struct you can do this :

>> s = struct;
>> t = linspace(3,5,20);
>> s = setfield(s,"FieldName",t);

You can append values to a table using concatenation as follows

>> t = table(1,2)
t =
  1×2 table
    Var1    Var2
    ____    ____
     1       2  
>> t2 = [t;table(3,4)]
t2 =
  2×2 table
    Var1    Var2
    ____    ____
     1       2  
     3       4  
>> t2 = [t;{3,4}]
t2 =
  2×2 table
    Var1    Var2
    ____    ____
     1       2  
     3       4
