Announcements
New The take-home Final Exam is now posted on the assignments page. Due Friday 5/18 in class.
The course syllabus has been modified. There will now only be 7 homeworks and the final exam will be a take home-exam worth 200pts. There is no longer the possibility to replace your lowest midterm exam score with the final. More details can be seen on the course syllabus page
here.
Here is the MATLAB code from class Thu 5/3:
ODE-examples.m. It implements several numerical ODE algorithms discussed in class.
Homework 7 is now posted on the assignments page. Due Thurs 5/10 in class.
Homework 6 is now posted on the assignments page. Due Tues 5/1 in class.
Here are the solutions to the second midterm exam.
The Homework 5 Due date has been changed to Tu 4/17 in class.
Homework 5 is now posted on the assignments page. Due Th 4/12 in class.
Midterm Exam 2 is scheduled to take place on Tuesday 4/10 in class. It will mainly cover material from the sections on Approximation of Functions, Interpolation and Least Squares. Please take a look at previous exams courtesy of Dr. Levy, now available on the resources page under Old Exams.
Homework 4 is now posted on the assignments page. Due Tu 4/05 in class.
There will now be an additional office hour for the course on Fridays from 3:00pm - 4:00pm.
Here is a an interesting article about the history use of splines in design.
Here is a code for generating a global polynomial interpolant of a function using the divided difference algorithm:
divdiff.m.
An interactive example for Runge's Phenomenon when interpolating the function $f(x) = 1/(1+x^2)$ with equidistant and Chebyshev nodes is now available on the
resources page.
An interactive example for the node polynomial $\omega(x) = \prod_i(x-x_i)$ is now available on the resources page.
Makeup material for the first midterm exam is now available here. It is due Thursday March 15 in class. No late assignments will be accepted.
Here are the solutions to the first midterm exam.
Homework 3 is now posted on the assignments page. Due Tu 3/13 in class.
The deadline for Homework 2 has now been moved to Thu 2/22.
Here is the code for generating the Newton Fractals: newton.m is a function implementing of Newton's method,
newton_fractal.m is a function which generates the images, and run.m is an m-file which calls
newton_fractal.m for specific function (here $f(z) = z^3-1$). Homework 2 is now posted on the assignments page. Due Thu 2/20 in class.
Homework 1 is now posted on the assignments page. Due Thu 2/8 in class.
