Cell contents reference from a non-cell array object ERROR

Hi everybody, error occurs in Ed=Ed{j};

I don't know what is it and will be grateful for any suggestion.

Ned=zeros(ne,1);
for i=1:ne
    for j=1:lc
        Ed=Ed{j};
        Ned(i)=bar3s(Ex(i,:),Ey(i,:),Ez(i,:),[E Ep(i,1)],Ed(i,:));
    end
end
--------------------------------------------------------------
function [es]=bar3s(ex,ey,ez,ep,ed)
 b=[ ex(2)-ex(1); ey(2)-ey(1); ez(2)-ez(1) ];
 L=sqrt(b'*b);

   n=b'/L;   G=[   n      zeros(size(n)); zeros(size(n))     n   ];

   E=ep(1); A=ep(2); Kle=E*A/L*[ 1 -1; 1  1];

N=E*A/L*[-1 1]*G*ed';
 es=N;

Ed{j} is the content of element j within cell array Ed, and you are trying to assign that value to the cell array itself Ed:

Ed=Ed{j}; %!!!!!

[Hamid]

Ed = cell(1, lc);

What should I do David?

[David Sanchez]

You might try something like this:

Ned=zeros(ne,1);
for i=1:ne
    for j=1:lc
        % Ed=Ed{j}; %%%%%no need for this line
        Ned(i)=bar3s(Ex(i,:),Ey(i,:),Ez(i,:),[E Ep(i,1)],Ed{j}(i,:)); % the cell content is plugged with no need of intermediaries
    end
end
