store each result inspite of re write updated answer i work in main file and call function from function file store each result of values which run in function file

function [branchcu,totalpowerloss,vpu,finalloss] = loadflow1(sys,DLF,BIBC,branch,result,BCBV)

v0=(12660+1i*0).*ones(branch,1);
P=sys(:,6)*1000;
Q=sys(:,7)*1000;
v=v0;

for k=1:20
I=-conj((P+1i*Q)./v);
delta_v=DLF*I;
v=v0+delta_v;
end

v_pu=[1+1i*0;v./12660];
voltage_perUNIT=abs(v_pu)';
vpu=voltage_perUNIT'

branchcu=abs(BIBC*I)

   for r=1:branch
  powerloss=branchcu(r)^2*sys(r,4);
   t1(r)=powerloss;
   end 
   total_powerloss=sum(t1)

end

when i call variables in command window it shown undefine variable,,how to store each element
