saving Iterations in the loop below

Somebody please help urgently. I want to save the values of iterations of Modata in the loop. The current code is not working.

    Ro = 0.05:0.1:0.45;          
  ii = 20*pi/180:20*pi/180:90*pi/180;          
  BGammaMax = 0.5:0.1:3;
  phi2 = 0:2*pi/60:2*pi;

L = [];
for Ro_s = Ro
  for ii_s = ii
   for bg_s = BGammaMax
       for phi2_s = phi2;
          L2 =sqrt( Ro_s*ii_s)+(bg_s*phi2_s);
          L = [L;L2];
          MoData = [Ro_s ii_s bg_s phi2_s L2]
         FN = (num2str(Ro_s), num2str(ii_s), num2str(bg_s), num2str(phi2), num2str(L));
         dlmwrite('myFile.txt',FN,'delimiter',' ');
        end
       end
      end
    end

It's repeat.

Ro = 0.05:0.1:0.45;
ii = 20*pi/180:20*pi/180:90*pi/180;
BGammaMax = 0.5:0.1:3;
phi2 = 0:2*pi/60:2*pi;

a = cell(1,4);
[a{end:-1:1}] = ndgrid(phi2,BGammaMax,ii,Ro);
z = cell2mat(cellfun(@(x)x(:),a,'un',0));
MoData = [z, sqrt(z(:,1).*z(:,2)), z(:,3).*z(:,4)];

or

[x4,x3,x2,x1] = ndgrid(phi2,BGammaMax,ii,Ro);
MoData = [x1(:),x2(:),x3(:),x4(1), sqrt(x1(:).*x2(:)), x3(:).*x4(:)];

pls what is a

[Andrei Bobrov]

The a - variable, cell array (1 x 4).

[Andrei Bobrov]

[x4,x3,x2,x1] = ndgrid(phi2,BGammaMax,ii,Ro);
L = arrayfun(@(a,b,c,d)RoT(a,b,c,d),x1(:),x2(:),x3(:),x4(:));
MoData = [x1(:),x2(:),x3(:),x4(:),L];

[Andrei Bobrov]

Please show RoT.
