How to use the fillmissing function to interpolate at certain points

Suppose I have some data at times t = 1:100, with some missing values.

I want to use fill missing function to interpolate only at certain data points e.g. at t = 10,20,30,40,50,60,70,80,90,100.

Sample points argument does not seem to be working.

You can directly use interp1 to interpolate at your desired time intervals.

t = 1:100;
v = zeros(1,100); % here v is the value u are interpolating
ti = 10:10:100;
vi = interp1(t,v,ti);

What if I want to fill up in between, like for example: at [2 3 4], then at [15:25] and so on?

yes just create a ti vector comprising of the values you need.

ti = [2:4 15:25]; % etc
