Hello

I have a program now,which open a file ,calculate some value and draw 2 graph.I open a file by using

    [filename, filepath] = uigetfile('Choose a binary file');
    fullname = fullfile(filepath, filename);
    txt = fileread(fullname);

Now if i have folder of 20 such files,store in a folder names ad rboo1.txt to rb020.txt how can I open it simultaneously and shall get my output

my code is

I am converting after reading this rb001 file to decimal.txt

            X=csvread('E:\decimal.txt');
            R = histc(X,0:255);% the no of occurence
            disp(' The no of occurence');
            [(0:255).' R(:)] 
            P = histc(X,0:255)/length(X);% the prob of occurence
            disp('The prob of occurence');
            [(0:255).' P(:)] 
            %%%%%%%%%%%%%%%%%Calculation of SigmaW  %%%%%%%%%%%%%%%%%%%%
            for i=1:1:256
                ay=P(i)-0.00391;
                ay=ay*ay;
                N=R(i)*ay;
                d2=d2+N;
                d=d+R(i);
            end
            S=d2/d;
            SigmaW=sqrt(S);
      plot(0:255,P);

My problem is I need this signaw individually for each file and want to save it after execution of each file,and plot for individual file,my code is working fine,with input file one by one but when I need to do it simultaneously for 20 such file..How can it be possible
