The question is not clear enough to be answered. What do you want to "simulate"? An elastic impact of a ball, after it was thrown in a specific direction considering air friction?
"does not change positions neither bounces up" - is this the actual state and you want to change it (them show us the ocde) or the wanted behavior and you search for a point to start programming?
"This takes place within a particular space that needs to be defined as well." - as reader in the forum, I cannot imagine, what you havbe in mind.
Please explain with details, what the problem is and ask a question concerning Matlab.
