my code runs correctly when lc is 1,I want lc>1 ;

Ed is 45*6 matrix and I think there is a way to assign Ed for lc>1 .

What can I do?

please help.

for i=1:lc
      ff=f(:,i);
  [a,r]=solveq(K,ff,bc);
  Ed=extract(Edof,a);
  end
----------------------------------------
function [ed]=extract(edof,a)
  [nie,n]=size(edof);
    t=edof(:,2:n);
    for i = 1:nie
        ed(i,1:(n-1))=a(t(i,:))';
    end

Store the various values of Ed for different iterations in a cell array

Ed{i} =extract(Edof,a);

or a 3D array

thisEd=extract(Edof,a);
allEd(:,:,i) = thisEd;

If you use a 3D array, be sure to preallocate before the loop starts

Ed=allED(45,6,lc);

Maybe you need to define Ed as a cell before the loop

Ed = cell(1, lc);
