Need to write a function that rotates cartesian coordinates

I have this homework problem and have no clue where to start. Wondering if the community can help me out. Professor is out of the question to ask for help on this one. We don't get along too well.

I submitted a zipped file. It contains the whole layout of what needs to be done.

Given coordinates, a matrix, turn coordinates around an axis. Make sure inputs are given by command window.

I'm not sure how to guide you without more information, tell us specifically what have you attempted so far and what are you trying to do but needs help with the coding. If you haven't attempted anything, maybe start from reading the help documentation on function and input.

I provided a word doc in the zipped file. And I know how to create a function that asks for input from the command window. It's for a class and I'm having trouble with this. The teaching assistant can't figure much out of it either since she has little experience. Really sorry for being horrible at explaining this.

I'm not sure where you submitted the file. If anything, it should be as an attachment. Please don't put it on the file exchange.

Look up rotation matrix or transformation matrix on Wikipedia. Your final function should take coordinates matrix and angle, and spit out

New Matrix = Rotation Matrix * Old Matrix as the answer.
