- Colloquium
- Amanda Tucker, University of Rochester
- “Multiple Zeta Values”
- Thursday April 7th, 4:00 pm
- Newton 204
- Usual extra credit for write-ups
- Exam 2
- Friday (April 8)
- Material since 1st hour exam (e.g., if, while, for, function handles, Newton, Riemann sums & trapezoid rule, etc.)
- Rules and format similar to 1st exam, especially open references, open computer
- Sample exam on our “Exercises” page
- Questions?
- Plotting rectangles (or trapezoids)
- Easiest is to build vectors of x and y coordinates for corners as you calculate
areas and plot each rectangle/trapezoid separately
![Rectangle starting at x(i) has coordinate vectors [x(i),x(i),x(i+1),x(i+1)] and [0,f(x(i)),f(x(i)),0]](rectangle.png)
- Easiest is to build vectors of x and y coordinates for corners as you calculate
areas and plot each rectangle/trapezoid separately
- (After exam)
- Start image processing in Matlab
- … which requires 3D arrays
- … which, as done in our book, require subarray indexing
- So read sections 9.6 - 9.8 in textbook
