Section 9.5 Quick Recap on Arrays

Up to this point, you should be able to do the following with arrays:

Create row vectors.
Create column vectors.
Create equally spaced arrays using the : operator.
Create linearly spaced arrays using the linspace() function.

Create arrays using all 1’s and all 0’s using the ones() and zeros() functions.
How to use the transpose operator ’.
How to address arrays and access the values they contain.

Whew! That is a ton. Good work!
