interpolation of gaze trajectory data

Hello, I have collected my data from Tobbi , eye tracker device, now I need to do some analysis. In particular I have focused on the gaze point trajectory ( I get the x's and y's of both eyes through the device for the duration of the recording ) . My problem is that this data has a lot of Nan, so I wanted to ask if there is a type of interpolation I can use on this data (I tried interp1 but I would need something a bit more specific for the type of data) or some pre-processing already done on matlab to be able to process my data and clean it up.

Thank you
