code:
global q
N_UE=[10 20 30 40 50];
N_SC=[60 70 80 90 100];
iwant = cell(length(N_UE),1);
for t= 1:length(N_UE)
for r= 1:length(N_SC)
G=rand(N_UE(t),N_SC(r));
N_SC_=ceil(N_SC(r)/N_UE(t));%round up to nearest multiple
C=repmat(diag(1:N_UE(t)),1,N_SC_);
iwant{t}=C(:,1:N_SC(r));%crop back to only needed cols
D = iwant{t};
unused_rows=1:N_UE;
q=1
while ~isempty(unused_rows)
N_UE_rows=ceil(sqrt(randi([2,numel(unused_rows)])));
if (N_UE_rows+1)==numel(unused_rows)
N_UE_rows=numel(unused_rows);
end
rows=unused_rows(randsample(length(unused_rows),N_UE_rows));
[~,idx]=find(ismember(unused_rows,rows));
unused_rows(idx)=[];
[E,E_part,P_part,U_part,V_part]=cluster_rows(G,D,rows);
EP{q}=E_part
PP{q}=P_part
UP{q}=U_part
VP{q}=V_part
q=q+1
end
All_EP=[cat(1, EP{:})]
All_PP=[cat(1, PP{:})]
All_UP=[cat(1, UP{:})]
All_VP=[cat(1, VP{:})]
end
end
-------------------------- ----------------------------
% function [E,E_part]=cluster_rows(G,D,rows)
function [E,E_part,P_part,U_part,V_part]=cluster_rows(G,D,rows)
global q
%extract the parts of the matrices
G_part=G(rows,:);
D_part=D(rows,:);
%sum along the the vertical axis to get indices for the non-0 columns
non_0=sum(D_part);
%Repeat the vector back to the same size as the partial matrix. It will be
%converted to a logical later on.
non_0=repmat(non_0,length(rows),1);
%create a copy of B, as that is the basis for C
E=D;
E_part=D_part;
%for all non-zero columns, replace the 0 positions with the values from A
E_part(non_0 & E_part==0)=G_part(non_0 & E_part==0);
% D_part(non_0 & D_part==0)=G_part(non_0 & D_part==0)
%paste the edited partial matrix back
% D(rows,:)=D_part
E(rows,:)=E_part;
P_part = rand(size(E_part)) .* (E_part ~= 0);
U_part=sort(E_part,'descend');
V_part=sort(P_part);
EP{q}=E_part
PP{q}=P_part
UP{q}=U_part
VP{q}=V_part
end
If i run the code i am getting
Error using cat
Dimensions of matrices being concatenated are
not consistent.
Error in (line 43)
All_EP=[cat(1, EP{:})]
could anyone help to overcome it.

You have
unused_rows=1:N_UE;
but N_UE is a vector. The right hand side of a colon expression should always be a scalar. MATLAB does not give a warning or error when you use a vector on the right side, but it will ignore everything except for the first element.

do you want me to do in the following way [E,E_part,P_part,U_part,V_part]=cluster_rows7(G,D,rows,t,r)

Yes. And remember to adjust the function declaration for the function to add those two parameters.
