How to do fourier transformation on time series data with Zero or 0 values?

03 December 2019 1 2K Report

I am trying to apply fourier transformation on a time series dataset which is having some entries with "0" and Negative values. It is failing with NaN error. Could anyone please suggest a work around keeping the flavour of the data intact.

Dear Saptarshi Das , can you please give an example. This Matlab example works well: plot(fftshift(abs(0*(1:1e4)))).
