Need help creating a two separate matrices; one matrix is a 5x5 and has ones in columns 1, 3, and 5. The other matrix is also 5x5, but in the elements in the fifth column are equal to the row number that they are on.

I'm supposed to use loops and/or conditionals to achieve the arrays. I'm not sure where to start; any help is appreciated!

I'm not sure where to start

The first line will probably be

A=zeros(5)

if you're looking for hints, check out the functions:

size()
ones()
zeros()

and this documentation on array indexing:

Thanks a bunch! I'll try running tests and see what I can come up with
