### Example 1

Create matrices for the data:

1. The forecast this week is as follows: Monday, a high of 76 degrees and a low of 40 degrees; Tuesday a high of 71 degrees and a low of 43 degrees; Wednesday a high of 69 degrees and a low of 40 degrees; Thursday a high of 66 degrees and a low of 40 degrees; and Friday, thanks to the incoming meteor, a high of 178 degrees and a low of 165 degrees.

### Example 2

There are three kinds of cookies for sale: lemon, chocolate, and lingonberry. There are 24 lemon cookies, 30 chocolate cookies, and 5 lingonberry cookies since no one likes them.
