Prelim 2 topics

Topics/ideas

• 2-dimensional array (matrix)
• 3-dimensional array (e.g., color image data)
• Character and string (array of characters)
• Cell array
• sort() and permutation indices
• File input/output
• Array (2-d, 3-d) algorithms/patterns: full array traverse, partial array traverse (e.g., rectangular subarray, triangular subarray)
• Nested loop patterns for all combinations
• Computing in type uint8
• Vectorized code (as discussed in lecture)

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

• Lecture: up to and including Lecture 19
• Discussion: up to and including Exercise 9
• Homework: up to and including Project 4
• Assigned reading: see Lecture notes through Lecture 19.

Read this note on vectorized code.

Do not use built-in functions that have not been discussed in class.

Matlab predefined (built-in) functions that may be needed for solving the exam problems will be listed. You are expected to know how to use them.

Matlab statements that students may not use:

• switch
• break
• continue
• return
• try, catch
