facing problem in reshaping the column matrix please help

clc;
close all;
clear all;
printlevel=3;
n=input('n=');

for kk = 0:n
    for ii = 0:n
        for jj = 0:n 
            
            E =   ((nchoosek(n,ii))/(2*n+kk+1))*((nchoosek(n,jj))/(nchoosek(2*n+kk,ii+kk+jj)))
        end
        
        ee(kk+1,ii+1) = reshape(E,n+1,1)
    end
end

Maybe you mean:

n = 3;
E = zeros(n+1, 1);  % Pre-allocate in wanted dimension instead of reshape
ee = zeros(n+1, n+1, n+1);   % Preallocate!
for kk = 0:n
    for ii = 0:n
        for jj = 0:n 
            E(jj + 1) = (nchoosek(n,ii) / (2*n+kk+1)) * ...
                        (nchoosek(n,jj) / nchoosek(2*n+kk, ii+kk+jj));
      %      ^^^^^^^^ 
        end
        
        ee(kk+1, ii+1, :) = E;
      %                ^    E is a vector, you cannot assign it to the
      %                scalar ee(kk+1,ii+1)
    end
end
ee

ee = 
ee(:,:,1) =
