Hello,

In Matrix, I should work with the Fourier transform of the max and min, I blocked out that how after every time I put a zero, check whether the max and min max and min are still, otherwise I have to look the new max and min.

I made the following attempt:

epse=0.01;
epsilon = 0.01;
MASQUE=ones(256,256);
somme = sum(MASQUE(:));
while(abs(somme)>epsilon)
      Auto_Cor1=Auto_Cor1.*MASQUE;
      G1=abs(Auto_Cor1).^2;
      Auto_Cor2=Auto_Cor2.*MASQUE;
      G2=abs(Auto_Cor2).^2;
      Auto_Cor3=Auto_Cor3.*MASQUE;
      G3=abs(Auto_Cor3).^2;
      XCor1=XCor1.*MASQUE;
      G4=abs(XCor1).^2;
      XCor2=XCor2.*MASQUE;
      G5=abs(XCor2).^2;
      XCor3=XCor3.*MASQUE;
      G6=abs(XCor3).^2;
      [A1 ID1] = max(Auto_Cor1(:));
      [A2 ID2] = max(Auto_Cor2(:));
      [A3 ID3] = max(Auto_Cor3(:));
      [M1 id1] = max(XCor1(:));
      [M2 id2] = max(XCor2(:));
      [M3 id3] = max(XCor3(:));
      M123=[M1 M2 M3];
      A123=[A1 A2 A3];
      MAXC=max(M123)
      MINA=min(A123)
      if     MAXC==M1
          trans_four_C=TF7;
      elseif MAXC==M2
          trans_four_C=TF8;
      else
          trans_four_C=TF9;
      end
      if     MINA==A1
          trans_four_A=TF1;
      elseif MINA==A2
          trans_four_A=TF2;
      else
          trans_four_A=TF3;
      end
      %%DC
      Matrice=abs(trans_four_C).*cos(angle(trans_four_C) - angle(trans_four_A))-epse*abs(trans_four_A);
      somme = sum(Matrice(:))
      if (abs(somme)<epsilon),break,end
      if somme>0
          [maximum indice] = max(Matrice(:));
          Matrice(indice) = 0;
          MASQUE(indice) = 0;
      else
          [minimum indice] = min(Matrice(:));
          Matrice(indice) = 0;
          MASQUE(indice) = 0;
      end
      somme = sum(Matrice(:));
  end
