help me about integral inside integral

Hello everyone,

I wrote a code for a function that includes inner functions and integral but I get confused I is working but not a professional way can you help me to write it more professional ? Thank you :)

aa=(k*l*vi/(wr*ccons));
bb=@(w) (((1+w/wr*l)*vi/ccons).^(k-1));
cc=@(w) (2.71.^((-((1+w/wr*l)*vi/ccons)).^k));
f3 =@(w)bb(w).*cc(w);
  for i=1:num;
dd=@(w)kr*(x1(i)-w);
dd2=@(w)kr*(x2(i)-w);
fw1 =@(w)f3(w).*dd(w);
fw2=@(w)f3(w).*dd2(w);
% x=in(:,3:4);
% Qscalarx = @(x)integral(@(w) kr*(in(:,3:4)-w)*(k*l*vi/(wr*ccons))*(((1+w/wr*l)*vi/ccons).^(k-1))*2.71.^((-((1+w/wr*l)*vi/ccons)).^k),0,x);
% Q = @(x)arrayfun(Qscalarx,x);
%  Q(x);
   Q1(i) = integral(fw1,0,x1(i));
  % fw2 = @(w) kr*(x2(i)-w)*(k*l*vi/(wr*ccons))*(((1+w/wr*l)*vi/ccons).^(k-1))*2.71.^((-((1+w/wr*l)*vi/ccons)).^k);
  Q2(i) = integral(fw2,0,x2(i));
   end
  Q=Q1'+Q2';
  Cwsum=dc(1)*(in(:,3))+dc(2)*(in(:,4));
  lam=abs(Pd+2.32-sum(in(:,1:4)'))';
  totalcost=Cthermal+(Q)+Cwsum+100*lam;

Thank you :)
