Stieltjes moment problem

The Stieltjes Moment Problem is a type of math problem that asks you to to find a function that matches a certain set of numbers. Those numbers are called moments because they come from a particular type of math formula, called a moment. In the Stieltjes Moment problem, you are given a set of moments and asked to find the function that matches them. To solve the problem, you must figure out what different parts of the functions look like (like finding things like the peak, the period, and the shape) and then put them all together in the right order to make the function that matches the given moments.
