Create matrices

Create the following matrices. Create an octave function that returns a matrix. Name the function as proposed in bold at the beginning of each task.

Please, use only methods that were discussed at the lecture. That is, for example, don’t use loops and functions such as repmat. And try to find a short solution, that is, don’t enter all the values manually.
