I have a 21x1 array in which every other value is NaN:

s=[0 NaN 5 NaN 0 NaN 0 NaN 5 NaN 0 NaN 0 NaN 5 NaN 0 NaN 0 NaN 5];

I need to make a straight line from one surrounding value to the other for each NaN. For this case, it would be the averages, like 0 NaN 5 would be 2.5, because the surrounding values are 0 and 5, which would make the NaN become 2.5.

Basically I need to replace all the NaNs in this fashion and plot the new array.
