Use a structure with fields in a loop - Outputs & indexing ??

Hello everyone,
I am using a structure to output all my results from a function organised in different fields. My struct contains 10 fields - and as my loop has 101 steps my struct ends up being a struct array (1*101) with 10 fields.
Some of my fields are numeric arrays e.g. Sig (6*1) and i want to use the first value of each of these Sig in the 101 fields to plot them. How could i do this easily?
The way i thought is:
hist_st_cell=struct2cell(hist_state);
Sig_cell=hist_st_cell(1,1,:);
Sig_mat=cell2mat(Sig_cell);
Sig1_plot=Sig_mat(1,1,:);
Is there a better suggestion?

Where S is your structure:
F = @(a)a.Sig(1);
V = arrayfun(F,S)

The first line defines an anonymous function:
The anonymous function accepts one input "a" (which will be a scalar structure) and gets the first element of its field "Sig". The second line applies this function to each element of your structure array (remember each element of any array is a scalar array).
