ECOR 2606 Lab Test #2 v2 Instructions: Submit two "script" files, one for each of the two questions. Call these files Q1.m and Q2.m. All values output by your scripts must be appropriately identified (e.g. "The value of ... is ..."). Just omitting the semi-colon from the command that calculates the value is not acceptable. If a "script" requires functions that cannot be implemented as anonymous functions you must use a "void" (i.e. no inputs, no outputs) function m-file with secondary functions. A brief reminder of how to do this can be found on the G:drive (scripts.pdf). 1/. (6 marks) Analysis of an engineering problem has produced the system of equations shown

### What students are saying

• 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.
