Prelim 2 topics

Topics/ideas

• 2-dimensional array (matrix)
• 3-dimensional array (e.g. color image data)
• Computing in type uint8
• Array (2-d, 3-d) algorithms/patterns: full array traverse, partial array traverse (e.g., rectangular subarray, triangular subarray)
• Characters and char arrays
• Linear search
• Cell array
• Vectorized code
• File input/output
• good programming style (store important variables, use meaningful variable names, semicolons at the end of variable assignment lines, ...)
• Will this exam be cumulative? Each question on prelim 2 will focus on the topics listed above, but you typically still need loops, conditionals, functions, comparison operators, functions, and other topics from prelim 1 to complete problems in prelim 2. So yes and no. There will be no linear interpolation on prelim 2 though.

Students are responsible for all material covered in lecture, discussion, exercises, projects, and the assigned reading:

• Lecture: up to and including Lecture 20. Not that object oriented programming will not be included in prelim 2.
• Exercises: up to and including Exercise 11
• Projects: Projects 1, 2, 3, 4, and 5
• Assigned reading: See “Lecture materials”, up to and including Lecture 20

Examples on how to use selected MATLAB predefined (built-in) functions will be given on the exam. Do not use any built-in functions that have not been discussed in lecture, discussion, homework, and assigned reading. Write scripts and functions as specified in each exam question; specifically, write functions and subfunctions only if they are requested.

Matlab commands that students may not use:

• switch
• break
• continue
• return
