How can I call a value in side the a function which is already evaluated.

%% knt i calculated here.
nf=max(elem(:,4));
maxfl=max(elf(:,1));
for flno = 1:1:maxfl
for i=elf(1,1)
for j=1:1:nf
p=CGx(j)-CGx(i);
au=[1,0,0;0,1,p;0,0,1];
bu=(au)';
kse=eval(['KSE',num2str(flno),'l']);
k1=kse(1:nodof,1:nodof);
eval(['Ktts',num2str(flno),'l','=[k1,-k1*au;-bu*k1,bu*k1*au]']); %Transformed Stiffness matrix of each floor (6x6)
end
end
end
%% I have to call the knt inside the loop, how can i call please suggest me.
function [t,k_hat, R, keyp, key,Keyp,Key, delu, k_T, delF_hat, deludot, u0, udot0, uddot0] = NewmarkNon( t,Ug, delF, dt, u_t, u_c,F1, KGf, C, MGf, Rt, Rc, R, gamma, beta, key, k_T,u,udot,uddot)
knt=eval(['Ktts',num2str(n),'l']);
end

"is there any way to proceed this operation without changing the code?"
No.

If you want to retrieve value of a variable from the parent workspace inside a function without passing it as argument onstead of normal eval do this
knt = evalin('caller','Ktts',num2str(n),'l'])

Postponing fixing your code by locking in using a hack like this is just going to result in it taking even longer to fix your code later.

It is not possible to do what you want to do using eval(). You will need to rewrite your code.

Do not store variables like KSE3l -- use a cell array like KSEl{n} instead. Or possibly a multidimensional array.
Likewise do not store into Ktts*l -- use a cell array like Kttsl{n} instead.
%% knt i calculated here.
nf=max(elem(:,4));
maxfl=max(elf(:,1));
for flno = 1:1:maxfl
for i=elf(1,1)
for j=1:1:nf
p=CGx(j)-CGx(i);
au=[1,0,0;0,1,p;0,0,1];
bu=(au)';
kse = KSEl{flno};
k1 = kse(1:nodof,1:nodof);
Kttsl{flno} = [k1,-k1*au;-bu*k1,bu*k1*au]']); %Transformed Stiffness matrix of each floor (6x6)
end
end
end
When you call your function (not shown in your code) pass in Kttsl as well.

n = something appropriate
knt = Kttsl{n};
end
