November - Introduction to Arrays

Ryan Roper -

This webinar was presented by Ryan Roper in November 2015. Below is a brief summary and video recording of the presentation. You can also download materials used during the presentation by clicking on the link(s) at the end of the article.

In many systems, you will want to create and manipulate elements that represent collections of data, rather than individual items. For example, you may want to create an element that represents your company's revenue for each of the last five years, or an element that represents the salmon population in each of 20 streams.


One way to do this, of course, would be to create separate elements for each object you wanted to model (e.g., five elements representing revenue, 20 elements representing salmon populations). To address these kinds of problems, GoldSim allows you to create and manipulate vectors and matrices (collectively referred to as arrays).

In a webinar presented in 2015, we discuss how to create and use arrays (vectors and matrices) in GoldSim. This includes discussions about the following topics: using array label sets, referencing array subitems, using arrays in expressions, using built-in array functions and using array constructors. Particularly useful is our discussion about array constructors, which is presented within the context of a hydrology application in which we calculate yearly summary statistics on monthly cumulative flow amounts.
