How to extract all variables from a structure

[Terry Duell]

Hello All,

I have a nested structure...

s =

  scalar structure containing the fields:

    data =

      scalar structure containing the fields:

        w1 =  237.60
        w2 =  244.20
        w3 =  150
        w4 =  3000
        r1 =  14.500
        r2 =  14.500
         .
         .
         .
        and so on

I see that I can use the function "getfield" to extract the structure  
"data" from the structure "s".
Is there a neat way of extracting all the variables from "data", (ie. so  
that they are simply unstructured variables) without having to separately  
reference each?

Cheers,
