k_est=k_p(bb,:);
XF_est=xf(bb).XF;
num_2=num_2+1;
kkk2(num_2,:)=k_est;
for iii=1:length(k_est)
X_re(k_est(iii))=XF_est(iii);
end
what is the problem in my four loop

What is k_est and what is its size (what are its dimensions)?

If k_est is a complex double, then how can you use it to index X_re in your statement
X_re(k_est(iii))=XF_est(iii);
??
Are you trying to define a "formula", sort of like a definition that for function f,
f(sqrt(2)) = 4.1293;
f(3.5) = 7.893;
?? If you are, then that is not possible in MATLAB, except in the case of a symbolic function being defined.
