Generate a vector of equations using loop

I have bunch of quadratic terms that I want to transform them into a vector of quadratic equations.

nlcon_funs=cell(size_con,1);

for i=1:size_con
    nlcon_funs{i}=@(x) x'*Qc{i}*x+lc{i}'*x;
end

nlcon=@(x) nlcon_funs;

Where nlcon is a vector of equations which is expected to have the form

   @(x) [x'*Qc{2}*x+lc{2}'*x;x'*Qc{2}*x+lc{2}'*x;...]

Since I have Qc and lc with pretty big size, it is impossible for me to write out nlcon directly, that's why I was trying to use a loop to create such form

 @(x) [x'*Qc{2}*x+lc{2}'*x;x'*Qc{2}*x+lc{2}'*x;...]

with given Qc and lc. However, it does not work as expected. Can someone tell me where I went wrong and how to fix it thanks!

If you are using fmincon or similar then the nlcon cannot be a vector of function handles: it would have to be a single function that invoked the vector of handles on each argument, such as

nlcon = @(x) cellfun(@(fun) fun(x), nlcon_funs)

But then you might as well

nlcon = @(x) cellfun(@(QC,LC) x'*QC*x + LC'*x, qc, lc)

which removes the problem of building the function handles.
