How do I interpolate values within a while loop?

Hi, I am using MATLAB R2020a on a MacOS. I am trying to remove outliers in real-time from a vector called 'cycle_periods' in a while loop by comparing each value to the exponentially weighted moving mean of the previously 'accepted' values. If the value in this vector meets 2 conditions, it is added to a new vector 'accepted_cycle_periods' and the exponentially weighted moving average is updated to include the newly accepted vector value. If the condition is not met, a zero is instead added to 'accepted_cycle_periods' as a place holder and the weighted moving mean is not updated. Is there any way of removing these zeros in real-time as soon as a new vector value from 'cycle_periods' is accepted, and then replacing the zeros by values based on a linear interpolation of the newly accepted value and the previously accepted value in 'accepted_cycle_periods'?
Any suggestions would be much appreciated. Thanks in advance.

You can use the interp1 function to interpolate the vector in the iteration when a new non zero value is added to the vector. You can refer the accepted answer for this question in the below link for details to interpolate a vector.
