hi

how would i use the for loop output to get the best value .. ie



for i = 1:15
for k = 1:15
tt = (a(i) + b) / y(k));
result = (tt *2) +1;
end
end

what i need is to be able to save the min value of ( result ) also the values of ( a ) and ( y ) where the min value of result happened ?

one of the many(!) solutions

amin=nan;
ymin=nan;
rmin=inf;
for ...
for ...
result=...
% insert >>>
if result < rmin
amin=a(i);
ymin=y(k);
rmin=result;
end
% insert <<<
end
end

ok here is the problem ..... i'm running a filtering operation on an image with different variables ..... i want to find the best result when changing a, b and y ..... when the result found .. i would like to mesh the correlation function (z) using the best values a,b and y



for i=1:15
for j=1:1
for k=1:15

h = filt(img,a(i),b(j),y(k));

[pce,PSR,AHH,info,z] = correlation (tgtfft,h); %% correlation function

PCE_Result(i+offset,k)=pce;
PSR_Result(i+offset,k)=PSR;
AHH_Result(i+offset,k)=AHH;
info_Result(i+offset,k)=info;
result = (AHH_Result/info_Result);

if result > rmin
abest = a(i);
bbest = b(j);
ybest = y(k);
rmin = result;

figure ,mesh(real(z)), axis tight , shading interp;

end
end
end
end


would you help me this please
