PP1=[1 1;0 1.3;0 0;1 0;0 1.2;2 0;1.5 1.5];
PP2=[0 1.1;1 0;1 1.3;1.5 0;0 1.7;0 10;2 0];
PP3=[1 0;0 1.1;0 1.8;1.2 0;1.1 0;0 0;0 1.7];
PP4=[1 0;0 1.4;0 0;0 1.7;1.9 0;0 1;1.4 0];
PP5=[1.8 1;1.3 1.2;0 0;0 0;0 10;1.5 0;0 1.1];
PP6=[0 1.2;1 1.1;0 0;0 1.3;0 0;1 1.5;1.5 0];
machine_power=[12;7;4;6;12;6;8];
cost=0.5;
E1=sum(bsxfun(@times,PP1,machine_power));
E2=sum(bsxfun(@times,PP2,machine_power));
E3=sum(bsxfun(@times,PP3,machine_power));
E4=sum(bsxfun(@times,PP4,machine_power));
E5=sum(bsxfun(@times,PP5,machine_power));
E6=sum(bsxfun(@times,PP6,machine_power));
z = [];
for a = E1
for b = E2
for c = E3
for d=E4
for f=E5
for g=E6
total_cost= C*(600*a+550*b+620*c+500*d+590*f+600*g);
z = [z; a b c d f g total_cost];
end
end
end
end
end
end
minVal=min(z)
the variables a,b,c,d...consist of 2 values/columns. How can I name them so that when I get the result I can identify that which column is selected for a,b, c, d, etc. e.g the value of 1st column of a=47 and 2nd is 54 so in the result matrix if 47 is selected it get the name 'route 1'and if 54 is selected it get the name 'route 2' likewise all the other variables(b,c,d,f,g) get 1st value as 'route 1' and 2nd value as 'route 2'

Time to graduate! Learn to use MATLAB. Numbered variables and named columns suggests you are trying to use MATLAB as if you are still using a spreadsheet.
