how can I fill each missed data point of my sensor data that is logged in every 15 minutes please? I have applied interploation into the dataset so I will get 96 data points every 24 hours. Now I need these gaps to be filled in with NaN so I will get plot which displays these gaps.

Compare the original vector of datetime value with the interpolated vector using ismember. This will create a logical vector identifying which values in the interpolated vector are the original data.
isOriginal = ismember(interpVector, originalVector);
interpVector(~isOriginal) = NaN;
