Why do you want to do this?
Currently you can trivially access the data in the structure (using basic indexing and fieldnames), so why would you want to make your data access more complex by splitting your data up into many separate variables?

Try this:
for k = 1 : length(particle)
% Extract the Position field for this row into a new variable.
thisRow = particle(k).Position;
% Now do something with thisRow....
end

You can try to understand a structure from the following code, in which several types of data are defined within a structure called s.
s.a = 1;
s.b = {'A','B','C'};
s.c.f = 4;
Then, you can extract from the structure s, an arbitrary data, for example, to extract the constant 1, in your script you can define the following, from the name with which it was saved in the structure, like this:
H = s.a;
Now, in the Workspace a variable called H with the value of 1 is defined.
