Numeric vs matrix array multiplication and division

In what case do you use ./ or .* to multiply two arrays vs / and * alone? I'm confused about these two questions below, can someone answer the two questions below and explain?

[Jiro Doke]

Perhaps start with doing a little bit of reading in the documentation:

Array vs. Matrix Operations

This is a fundamental concept in MATLAB, and there are lots of related pages in the DOC.

Good luck!

I've already read that and it's still not clear to me

\ this is mldivide. solves the system of linear equations A*x = B.

/ this is mrdivide. perform right-matrix division, which is same as A*inv(B)

./ this is element by element division.

/. or ./. there are no such operators in MATLAB.
