Hello guys,

I am using two variable named as "P" and "R" in the my routine with fix value. Now, i would like to use multiple set of value instead of one value and caculate the final optimal solution based on that range.

Practical explanation:

What i am using

P= 12

R=18

and using these value in my routine (Routine made of different formulas)

So, now i would like to give value are as

P= 2 to 30

R= 6 to 25

So finally, i would like to do it this two things

1)Calculate the answer from routine at each P (2 to 30) and respective R (6 to 25) value , how can i do it ?

2)Practically, I knows the what answer range from routine is suitable for me. Answer should be in the range of 10 to 12. If P and R parameters from the above set gives the asnwer in the range of 10 to 12, then routine should show me those respective P and R values at the end. So, i can use it those best P and R values in the real life.

Explanation: the Answer range is suitable for me (10 to 12)

If any of P and R values able to satisfy this condition (If answer from the routine gives the value in between 10 to 12) then those values of P and R should show at the end .

Do you think, it is possible ? Any solutions from your side, will be gratly appreciable.

Thanks a lot

Do you think, it is possible ? as you are expert from the matlab. I am not using Matlab too much. Any solutions from your side, will be highly appreciable.

Thanks a lot

在 MATLAB Online 中打开

[Pgrid, Rgrid] = meshgrid(2:30, 6:25);      % all combinations of P and R values
z = zeros(size(Pgrid));
for i=1:size(Pgrid, 1)
    for j=1:size(Pgrid, 2)
        P = Pgrid(i, j);
        R = Rgrid(i, j);
        % Your function
        z(i, j) = your_function(P, R);
    end
end
[zmin, idx] = min(z, 'all');
pmin = P(idx);
rmin = R(idx);
