Lists of values provide a lot of important information. You can gain further information by sorting lists either in ascending or descending order, or reversing a list that you've already created.
- [Instructor] List of values…provide a lot of important information.…You can get further information by sorting lists…either in ascending or descending order,…or reversing a list that you have already created.…In this movie, I will show you how to sort your list,…how to reverse its order,…and also how to pad or expand a list…so it has the exact length that might be required…for some calculations.…I've opened a blank Mathematica notebook,…so I need a list of values to work with.…So I will start by creating a list…called hlist, equals,…then a left curly bracket…and then the value's one, eight,…seven,…one, two,…six,…another comma, and then the last three values,…three,…five,…four.…
Then a right curly bracket to close the list definition…and Shift + Enter…and my list is in place.…If you want to sort the values in your list,…you can do that using the Sort command…and you can either go in ascending order or descending order…or as Mathematica calls it, Greater,…which puts the highest values in the front of the list,…or Less, which puts the lowest values…
