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

4 views (last 30 days)
%% 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

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.
