How to avoid overwriting inside a for loop?

I'm using repmat inside my for loop. But at the end of the loop, it saves only the value of last iteration repeating that last value alone. How not to overwrite the values of repmat and extract all the values of iterations.

frame=repmat(FR,1,size(centreDark(:,1)))
What do you think the purpose of this line is? What are you trying to do with it?
The loop does indeed not use the indexing variable FR to save anything from one iteration to the other so it does, indeed, overwrite all the variables you create each loop.
The question is, what do you intend/want?

Hi,
Instead of declaring “frame” as an empty array, declare it as an empty cell array.
frame={};
And inside for loop, assign the return value of repmat function to “frame{FR}”.Make the following changes in your for loop which may solve your problem.
frame{FR}=repmat(FR,1,size(centreDark(:,1)));
fr=frame{FR};
Now, the cell array “frame” stores every value of each iteration.
