How to inherit values from for loop into if else loop?

This is my code :
for i=1:n
Area(i)=k(i).Area;
Diameter(i)=sqrt(4*[k(i).Area]/pi);
MajorAxis(i)=k(i).MajorAxisLength;
end
Now I want to use the MajorAxis value into if else loop. Eg :-
if MajorAxis(i) < 0.002
Clay(i)=MajorAxis(i);
end
But the (i) values from for loop are not being inherited.

This is unclear: "i values not performing the if else loop". I cannot imagine, what this should mean. There is neither an "if else loop", nor do loop counters "perform" anything - most of all not outside the loop.

There is no magic "inheriting" of loop counters. I think the main problem is hiddon in your formulation "if else loop": The if command is not a loop.
You have to include the if into the loop:
Area = zeros(1, n); % Pre-allocate!
Diameter = zeros(1, n);
MajorAxis = zeros(1, n);
Clay = zeros(1, n);
for i=1:n
Area(i) = k(i).Area;
Diameter(i) = sqrt(4*[k(i).Area]/pi);
MajorAxis(i) = k(i).MajorAxisLength;
if MajorAxis(i) < 0.002
Clay(i) = MajorAxis(i);
end
end
Or you can omit the loop:
Area = [k.Area];
Diameter = sqrt(4 * Area / pi);
MajorAxis = [k.MajorAxisLength];
Clay = zeros(1, n);
Index = (MajorAxis < 0.002);
Clay(Index) = MajorAxis(Index);
