Kt=rand(6,6);
u=rand(6,6);
for i=1:1:6
for n=1:1:5
fr(:, i)=Kt*u(:,i) % i am try to call earch column of u here for multiplying with Kt, if i am wrong please correct me.
eval(['fr',num2str(n),'=Kt*u(:,i)'])
end
end
%%% Now i want to call each element of fr one by one how can i call it.

Hard to understand what you are trying to do. Eval statement makes no sense as well as the douple for-loop. Eval would be overriding each i-loop to the same values. Why not just:
Kt=rand(6,6);
u=rand(6,6);
fr=Kt*u;
Then index into fr. To call each element in fr,
for k=1:numel(fr)
fr(k)
end

@David Hill sir, please correct me.
ut=rand(15,1);
uy=([0.84;0.384;0.784]);
eval (['U_y','=[u_y;u_y;u_y;u_y;u_y]']);
for n=1:15
if ut(n,1)<=U_y(n,1)
ut(n,1)=ut(n,1);
else
ut(n,1)=0;
end
utt(:,1)=ut(n,1); %% i want to store the ut as a utt in a column
end
