i am trying to get how many times each iterations have repeated, which I have got using repmat. But at the end 'FRAM_FINAL' returns only the value of last iterations.
for FR=1:numimgs
%To read in all images in TIFF-file
output_image2=imread('C:\Users\user\Desktop\Photometrics_2x bin_video2.tif',FR);
ii=output_image3 - meanImage
I2 = mat2gray(ii);
qq=fibermetric(I2, 38,'ObjectPolarity','Bright');
[centreDark1, radiiDark1]=imfindcircles(qq, [Rmin Rmax],'Sensitivity',0.87,'ObjectPolarity','bright');
centreDark = [centreDark;centreDark1];
radiiDark = [ radiiDark;radiiDark1];
Right now the final answer i am getting for the range FR=1:numimgs where numimgs=120
obtained result 120 expected answer: 1
120 1
120 2
120 2
120 so on
120 120
so on 120

In the given code, FRAM_FINAL value is updated at every iteration. To make the vector “FRAM_FINAL” hold the results of each iteration, I would suggest concatenating the “FRAM_FINAL” at each iteration with its respective result using cat function.
For more information on concatenation, refer the following link

Note that for efficiency the MATLAB documentation recommends preallocating the output array before the loop, and using indexing into the array within the loop:
