Stretching out an array

Question

I\'ve got a vector of samples that form a curve. Let\'s imagine there are 1000 points in it. If I want to stretch it to fill 1500 points, what is the simplest algorithm that g

Answer 1

Simplest option I can think of is just a fn that expands the array based on mean averages, so:

x,y,z

becomes

x, avg(x,y), y, avg (y,z), z

If you need more data points, just run it multiple times on the vector.
