Mathematical Built-In Functions, Predefined Constants, Adding Comments
Today’s lesson will cover adding comments to your code + built in functions in MATLAB. First, there are two commands that can pull up full lists of built-in elementary and special functions, respectively. Built in function means the command is already “built-in” to MATLAB, so if you type it out MATLAB will know what you…
