Put this:

A = 20;

I already stated A value and B value are generated by code.Once the value are generated i want them to make them equal wantedly.

Do you mean that you want to work backwards from A = 20 to figure out what input you would have needed to use in the process that generated A=10 in order for it to have generated A=20 instead ?

yes.I want to work backwards.

I have posted question which needs to be executed backwards with respect to the code:

code:
A=[ 12 11 10 9;
8 7 6 5;
4 3 2 1]
B=[1 2 3 4;
5 6 7 8;
9 10 11 12]
C= partitions(3)
total = length(C)
idx = randperm(total,1) 
D = C(idx)
partdisp(D)
for len_partition=1:length(D)  
    for len_cluster=1:length(D{len_partition})
          display_user_inside_cluster=(D{len_partition}{len_cluster})
                for b =1:size(B,2)
                    for a =1:size(A,1)
                         rate(a,b) =((A(a,b)).*(B(a,b)))
                    end
                end 
        overallrate(len_cluster)= sum(sum(rate))
    end
end
totalrate=sum(overallrate)

Based on the totalrate i want to execute the command partdisp(D).Could you please help me on this.
