??? In an assignment A(I) = B, the number of elements in B and I must be the same. matlab error

I have problem with indexing

my code is:

function [d] = tazisko6(A)

d1=length(A); d2 =length(A{1});

   s=0; 
   for i=1:d1
       for j=1:d2
           s=s+(A{i}{j});

       end
       if d2~=1
       d=s/2;
       else

       d=s;
       end

   end

[t1,t2]=size(Z)%cell 1x3 cell

for i=1:t2 [d]=tazisko6(Z(i))

   end

ouput: d=2.8000 3.6000 17.2000

d= 27.7500   35.3500   50.3000

d =

    2.4000    3.5500   17.7500

i want to have ouput in the form d(1)= 2.8000 3.6000 17.2000 d(2)= 2.8000 3.6000 17.2000 d3(3)= 2.4000 3.5500 17.7500

when I add to the source code variables i

for i=1:t2 [d(i)]=tazisko6(Z(i))

   end

matlab error ??? In an assignment A(I) = B, the number of elements in B and I must be the same

Can you help me with indexing ?

Thanks

Can you detail this matrix A?

You forgot to give the error message. Don't snip or paraphrase. Copy and paste ALL THE RED TEXT so we can tell what is going on. And I don't understand this "when I add to the source code variables i

for i=1:t2 [d(i)]=tazisko6(Z(i))

   end"

You're not adding anything to i - it's the same as the first time you do that, and anyway, you're not adding anything to i, you're specifying that it take on a sequence of numbers: 1, 2, 3, 4, ...t2. So I don't see what you did differently in that chunk of code that is different than the first time you called it when it worked and you got d as an output.

I think you might need to initialize d here before making the addition

this is my code full

clear,clc

MON = [2.8 3.6 17.2; 5.4 8.3 15.8; 2.5 3.2 17.6; 9.9 10.7 13.6; 5.5 8.9 15.5; 9.7 11 13.9; 2.3 3.9 17.9; 5.7 8.1 15.1; 9.4 10.5 13; 9.9 13.2 13.7];

    [m,n]=size(MON)

    T=input('Zadaj počet typickych bodov :')%uzivatel zada koľko chce mať typickych bodov
       for i=1:T %Pociatocne typicke body

        TAZ=MON(1:T,:);

    end

    TAZ

     [r,s]=size(TAZ)%rozmery TAZ

     Z=cell(1,T)%vytvorenie zhlukov

z=1;

        for i=1:m
     for j=1:r

    B = MON(i,:);

    Z1(j)= euklid6(TAZ(j,:),B);%euklidovska vzdialenost

     end

      Z1

      minD = min([Z1])%minimalna hodnota
      [i_min,j_min]=find(Z1==minD)%indexacia minimalnej hodnoty

      [e,f]=size(Z1)

      for h=1:f
          if (Z1(h) == Z1(j_min))

          Z{h}{z}=B
          z=z+1;
          end
      end

     end

      Z;   

      d1=length(Z)

      for i=1:d1 %zmaze prazdne miesta
          Z{i}(cellfun(@isempty,Z{i})) = [];
      end
      Z

    [t1,t2]=size(Z)

   for i=1:t2
      d(i)=tazisko6(Z(i))

   end

    matlab error ???  In an assignment  A(I) = B, the number of elements in B and
 I must be the same.

Error in ==> knew at 78 d(i)=tazisko6(Z(i))

??? In an assignment A(I) = B, the number of elements in B and I must be the same.

Error in ==> knew at 78 d(i)=tazisko6(Z(i))

function [d] = tazisko6(A)

d1=length(A); d2 =length(A{1});

   s=0; 
   for i=1:d1
       for j=1:d2
           s=s+(A{i}{j});

       end
       if d2~=1
       d=s/2;
       else

       d=s;
       end

   end

I do need each iteration stored in memory, so that I could continue with that work.

Thanks

It is not complete (full). I get this when I try to run it:

Undefined function 'euklid6' for input arguments of type 'double'.

Error in test3 (line 28)
    Z1(j)= euklid6(TAZ(j,:),B);%euklidovska vzdialenost

You did not supply euklid6() and you didn't tell us what number or letters to input at the input prompt. Please make it easy to help you, not hard . http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer.
