How can I save the result obtained from the For loop in one variable ?

I used a for loop to calculate the radius for each picture of the circle in the folder.

However, not all data are accumulated in the radius variable, only the radius value for the final i value is obtained.

I want to save the circle radius values of all photos to an excel file.

Any help would be appreciated.

You may assign another variable with index which stores the result within the loop

for i = 1:10
%....
%....
    [centers, radii] = imfindcircles(A,[15 30]);
    centers_combine{i} = centers;
    radii_combine{i} = radii;
%....
end

More robust with preallocation:

N = 10;
centers_combine = cell(1,N);
radii_combine = cell(1,N);
for k = 1:N
    %....
    %....
    [centers, radii] = imfindcircles(A,[15 30]);
    centers_combine{k} = centers;
    radii_combine{k} = radii;
    %....
end
