Hi to all, I have this code for read a sequential ascii file (1500x1500) and substuite a NaN_value with 0 and rewrite that. Now I want introduce in the for cycle a string code to create a new variabile (maybe a structure matrix or something like that), with for each cell there is a 'history matrix' for these cells derived for each loaded ascii file.

if true
clear all
D = dir(fullfile('Daily_cum_*.asc'));
mkdir('displacement maps_NaN Value')
    parfor k =1:numel(D)
    fid = fopen(fullfile(D(k).name), 'rt');
    filename = D(k).name ;
    A=importdata(filename, ' ', 6);
    B=A.data;
    Nan_value = sscanf(A.textdata{6,1},'%*s %f'); 
    DC = changem(B, 0, Nan_value);
    C{k} = DC 
    cd('displacement maps_NaN Value'); 
    dlmwrite(filename,DC, ' ');
    cd ('..')
    fclose(fid);
end
  end

Is it possible ? I tried to do that with this code:

if true
  for k =1:numel(D)
  hh=0;
  ggg=0;
    for gg=1:1500
      ggg=1+ggg;
      fff=0;
     for ff=1:1500
         fff=fff+1;
     hh=1+hh;
  ridotta{k}(ggg,fff)=C{k}(gg,ff);    
 newdata2{hh}(k,1)=C{k}(gg,ff);
  end
  end
end
end
