“An Elementary Construction of Tessellated Surfaces”
Jonathan Pakianathan
University of Rochester
Monday, March 2, 4:00 - 5:00, Newton 201
Extra credit for summaries
Exam 1 is next Monday (March 2)
Material since beginning of semester (e.g., expressions,
variables, vectors, matrices, plotting, scripts, functions, etc.)
3 - 5 short-answer questions
May ask you to write fragments of Matlab code, but syntax
details won’t count for much in grading
Whole class period
Open book, notes, computer for reference; closed person
I’m out of town Friday March 6
Class will be review of test solutions
How do you feel about video chat?
Willing to try it
If you want to “host” part of the Geneseo end of
the chat, install Google hangout software/app for Friday class
Questions?
Designing and Testing Programs
“Designing and Testing Programs” video
Planning process =
Goal to code for
Planning (id problem, input, outputs)
Check for examples, especially special cases
Find algorithm
Translate algorithm into programing language
Test on same multiple examples
Examples of examples for matrix lab
Things to test
Matrices for transformations (i.e., does what you think
scales stickperson really do so, etc.)
Changes to stickPerson function
Examples
Identity matrix (edge case)
Important transformations (rotation, dilation, shear)
