| Review of Last Time | 2/1 Session Links |
In our last session, we learned about four important concepts. Two of them are computational — running sums and running differences — and two are infrastructural: named parameters and reference types. The computational techniques are broadly applicable in modeling, and the infrastructure concepts apply not only in modeling but also in many other kinds of spreadsheet work.
Typically, people do figure out the computational techniques on their own — you don’t really need a course to learn how to do them. But it’s much more unusual to figure out the advantages of user-defined names or mixed references on your own. Check around amongst your acquaintances who use spreadsheets to see what they know. You might be surprised to learn how advanced you already are.

For many of you, matrix multiplication and array arithmetic are new ideas. It’s easy to get lost in the details of how they work and then forget about why we use them.
To keep a clear view of the forest and avoid focusing only on the trees, remember why we use matrix multiplication and array arithmetic. Briefly, we use them because we find that it’s very often helpful to decompose a problem into parts (analysis), then do calculations on the parts, and finally reassemble the final solution from the results of those partial calculations (synthesis).
Matrix multiplication and array arithmetic provide us with very convenient methods for performing those intermediate calculations on the parts. They’re the tools that make analysis and synthesis so powerful.
