Creating functions Important feature of any language User-defined functions can be thought of as a programmer’s ability to extend a language. How can we create them???

Our focus... M-files We will focus mainly on user-defined functions and learn how to write a complex program Our basic building block is .... function Output=nameOfProgram(Input) Body of Algorithm Output=...; ... but we will learn how to call functions (by other functions) organize programs by ”abstract”ing blocks of code design subfunctions of a function

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
