MATLAB: Value of variable is changed in iteration

loop iterationMATLAB

a=[2 2.8];b=[2.8 3];c=[2.5 3];d=[2 2.8];e=[2.5 3];f=[2.8,3];g=[2.5 3];
m=[];
for z=a;
    for y=b;
         for x=c;
            for w=d;
                for v=e;
                    for u=f;
                        for t=g;
f=48*z+33*y+10*x+37*w+30*v+45*u+64*t;
m=[m;z y x w v u t f]
                        end
                    end
                end
            end
        end
    end
end
the 5th iteration shown is result is 
m =
            2          2.8          2.5            2          2.5          2.8          2.5        648.4
            2          2.8          2.5            2          2.5          2.8            3        680.4
            2          2.8          2.5            2          2.5            3          2.5        657.4
            2          2.8          2.5            2          2.5            3            3        689.4
            2          2.8          2.5            2            3        689.4          2.5        31560
and so on the values of 6th colume are changed while I have given the values f=[2.8 3]..why it is selecting 689.4 in next iteration?

Is this what you are trying to do?
a=[2 2.8];
b=[2.8 3];
c=[2.5 3];
d=[2 2.8];
e=[2.5 3];
f=[2.8,3];
g=[2.5 3];
[A,B,C,D,E,F,G] = ndgrid(a,b,c,d,e,f,g);
result = [A(:),B(:),C(:),D(:),E(:),F(:),G(:)];
temp_var = (48 .* A) + (33 .* B) + (10 .* C) + (37 .* D) + (30 .* E) + (45 .*F) + (64 .* G);  
result = [result, temp_var(:)];
