arranging a matrix

thanks

now the doubt is that,

when I display the [c] matrix it shows 2*7 matrix

And workspace shows 240*7 matrix.

the problem is that

>>a=rand(2 ,7);

what should be the elements.

for my code I got 2*7 matrix with element values different for each iteration that values I want to display in matrix [c].

actually i am working on iris recognition.

for feature extraction.I use wavelet decomposition at level 5 then applied 2 D gabor filter for 6 orientation & 4 scales. i.e 5*4*6=120 for horizontal & 120 for vertical details;for obtained detail coefficients i.e vertical & horizontal details, then moment invariant are computed which is a set of seven element row vector.

such two vectors for vertical & horizontal details are obtained.that are represented in a matrix & formed a matrix of 2*7.

>>for i = 1:level,
>>
>>for k=1:p
>>  for n=1:N
     % create template for horizontal component
     polar_array=hdi;%hdi is horizontal detail.
     [template,mask] = encode(polar_array, nscales, minWaveLength, mult, sigmaOnf);
      F=template;
     [phi] = invmoments(F);
     phi=[phi(1) phi(2) phi(3) phi(4) phi(5) phi(6) phi(7)];
     horzmi=ceil(phi);%hormi is horizontal moment invariants

       disp('horzmi');
       disp(horzmi);

     % create template for vertical component
      polar_array=vdi; %vdi is vertical detail coefficient.
      [template,mask] = encode(polar_array, nscales, minWaveLength,  mult, sigmaOnf);
      F=template;
      [phi] = invmoments(F);
      phi=[phi(1) phi(2) phi(3) phi(4) phi(5) phi(6) phi(7)];
      vertmi=ceil(phi);%vertmi is vertical moment invariants.
       disp('vertmi');
      disp(vertmi);

      C=[vertmi;horzmi];

      disp ('feature vector');
      disp(C);
      end
  end
  end

Now from this code I want to generate a matrix of 240*7.where matrix C is 2*7 matrix.

will you suggest me for matrix creation.

Before the code:

allC = zeros(240,7);
R = 1;

In the code after you disp(C),

allC(R:R+1,:) = C;
R = R + 2;

At the end, allC will be your 240 * 7 matrix.
