Simple Linear Interpolation using Interp1

Hi all. I'm fairly new to Matlab and I'm just trying to interpolate.
I have a [1 12] time vector that represent 12 hours. I also have a temperature vector that only has 10 values because 2 of them are missing. I understand that the sizes must be equal to use interp1. This is what I have so far:
time = [1 2 3 4 5 6 7 8 9 10 11 12];
temp = [10 12 15 13 [] 16 16 18 [] 15 21 20];
points = [1 2 3 4 5 6 7 8 9 10 11 12];
y = interp1(time,temp,points,'linear')
The empty matrices are where I don't have available times. I'm trying to use all of this data to linearly interpolate temperatures for all entries in my points array.
Thanks so much :)

May I have a question, is it possible to interpolate the data (NaN) if the x and y does have the same length in 3D plot.
Thank you !
