Download inpaint_nans from the File Exchange. Although interp1 would also have been able to solve the problem too. inpaint_nans is far simpler to use for this though.

This is easier?
k = find(~isnan(x));
y = interp1(x(k),y(k),1:numel(x));
It is not difficult. But you cannot claim it to be simpler to use interp1 here.

data = [3, NaN, NaN, 7, NaN, NaN, 2, NaN, NaN, 19, NaN, NaN, 12];
miss = isnan(data);
data(miss) = interp1(data(~miss), find(~miss), find(miss))
