Lagerstrom Note re. Code and Display In the code examples that follow, we will often have the results displayed simply by leaving off the semi-colon at the end of assignment statements. (The results will be displayed in a simulated Command window.) In addition, we will assume that the display format has been set to “format bank” (i.e., results displayed to 2 decimal places), simply to save space. Finally, the display of the results will have blank lines in it for readability, but the code that would create those blank lines (e.g., disp(‘ ’) ) will not be shown in the code examples (again, for readability’s sake).

    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.
