MATLAB: How to fill values between two values.

Question

A = [1 0 0 0 2 0 3 0 0 0 0 4 0 5 ….]

B = [1 1.25 1.5 1.75 2 2.5 3 3.2 3.4 3.6 3.8 4 4.5 5 ….]

Is there a function for this?

Answer 1

You could use interp1:

>> A = [1,0,0,0,2,0,3,0,0,0,0,4,0,5];
>> X = find(A);
>> B = interp1(X,A(X),1:numel(A))
B =
  1.0000   1.2500   1.5000   1.7500   2.0000   2.5000   3.0000   3.2000   3.4000   3.6000   3.8000   4.0000   4.5000   5.0000
