Your HW answers must contain your ID, Last Name, First Name, and the number of the
Discussion Section in which you are enrolled.
The purpose of HWs is absolutely NOT for the mere assignment of grades.
purpose of HW assignments is to engage the student in the process of learning the material
of the course and the material that the instructor believes to be instructive.
As such, your
work should be your own and reflect your effort in the learning process.
As a result, you
are not to consult the notes, HWs, HW solutions, etc., of other courses or past offerings of
Of course, you may discuss the material of this course with other students of
this class; however, your work must be your own.
Write a MatLab code for the
Please modify the posted template
for this problem, and use the “diary” utility of Matlab.
As you know, that utility will
allow you to place your code and its output to the diary file; it is a hard copy of that file
that you are to submit with your HW.
Please follow the format of that template for your
For each iteration, the output should include x
, and f
following, not including the secant code, is an example of the interactive input and the
output corresponding to the “interest” problem of HW1.
Your stopping condition should
between two adjacent iterations; you may also include a
tolerance with respect to f.
Please follow this format, including your name, etc.
Apply your secant code to the Archimedes problem of HW1; for the two initial points,
use 0.95, 3.0.
What do you observe?
What does this imply about finding a root of a
polynomial that is supposed to be an answer to a practical problem?
