Problem 72. Interpolator

Created by Cody Team

Solve Later

You have a two vectors, a and b. They are monotonic and the same length. Given a value, va, where va is between a(1) and a(end) find the a(n), a(n+1) that flank it. Now interpolate the value, vb, such that it is proportionally between b(n) and b(n+1).

va can land exactly on a value of a.

WTF!
I know the function interp!! but I thougth I must program it... :-(

That's true, the instructions here do indicate that you're supposed to program it from scratch (e.g. find a(n) & a(n+1)).

For convenience, it would be useful if the code input variables were related to the variables listed in the solution window. We are given a, b, alpha, and beta in the Test Suite; the function that we are to type involves vb, va, a, and b. Sure, we can update it, but it just seems careless.
