You can use STRUCT2CELL to convert the struct to a cell at first:
S = struct('Field1', 1, 'Field2', 2, 'Field3', 3);
C = struct2cell(S);
disp(C{1});
disp(C{3});
% A partial list of values:
x = [1, 3];
D = C(x);

@Andrei: Is FIELDS documented now? Otherwise I'd suggest the older and documented FIELDNAMES.

It works like this:-
P.variable = rand(20,1);
x = [4 5 6 9];
for ii=1:4
P.variable(x(ii)) = ii;
end

If i understand correct, it can be done with the command
'fieldnames' it returns the names of the fields in a cell array.
p.a=1
p.b=2
p.c=3
name=fieldnames(p)
p.(name{1})
