How to store the value in 'for loop' to be compared in the next iteration for the same for loop. if the value obtained is lesser than the previous value, i have to replace it with the new one.
In the following code, the Ploss that we get in the first iteration have to compare with the Ploss we get in the second iteration. And if Ploss of second iteration is less than the first one, the value is stored. And continue till max ieration is reached. How to code for such problem??
for iter=1:10
for i=1:5
.
.%do something
.
Ploss(i)= objfun(i);
end
end

Exactly as you have written it as text: "if the value obtained is less than the previous value, i have to replace it with the new one":
Ploss = inf(1, 5);
for iter = 1:10
for i = 1:5
...
% Compact solution:
Ploss(i) = min(Ploss(i), objfun(i));
% Or more literally:
c = objfun(i);
if c < Ploss(i)
Ploss(i) = c:
end
end
end

@Jan whai if the Condition is changed as given: Here if the ploss(i2) obtained is less than previous value i want to replace it.
for iter=1:10
for i=1:5
%do something
ploss(i)=losses(i)
end
for i1=1:2
%do something
ploss(i1)=losses(i1)
end
for i2=1
% do something
ploss(i2)=losses(i2)
end
end

I'm not sure, if I understand you correctly, but this should work in exactly the same way:
ploss(i2) = min(ploss(i), losses(i2));
or
if anything < anotherThing
value = anything;
end
