This course is an introduction to modern methods for the numerical solution of initial
and boundary value problems for systems of ordinary differential equations,
stochastic differential equations, and differential algebraic equations.
We will discuss the principal classes of numerical methods and of their theory,
including convergence and stability considerations, consistency order, step size selection and adaptivity,
the effects of stiffness, geometric integration, invariant and Hamiltonian dynamics.

Written homework and several computational projects will be assigned.
The suggested programming language for computer assignments is Matlab, software produced
by The MathWorks.
The Matlab language provides extensive library of
mathematical and
scientific function calls entirely built-in.
Matlab
is available on Unix and Windows in the university computing labs.
The full set of manuals is on the web in
html
and also in
Adobe PDF format. The "Getting Started" manual is a good
place to begin and is available both in html
format and in Adobe
PDF format. The full reference manual as well as manuals for each
of the many toolboxes are all available.

### Disability Resource Services

If you have a disability for which you are or may be requesting an
accommodation, you are encouraged to contact both your instructor and
Disability Resources and Services, 140 William Pitt Union,
412-648-7890 or 412-383-7355 (TTY) as early as possible in the term. DRS will verify your disability and determine reasonable accommodations for this course.
### Academic Integrity

Cheating/plagiarism will not be tolerated.
Students suspected of violating the University of Pittsburgh Policy on
Academic Integrity will incur a minimum sanction of a zero score for the quiz,
exam or paper in question. Additional sanctions may be imposed,
depending on the severity of the infraction.
On homework, you may work with other students or use library resources,
but each student must write up his or her solutions independently.
Copying solutions from other students will be considered cheating, and handled
accordingly.
### Statement on Classroom Recording

To address the issue of students recording a lecture or class session, the University's
Senate Educational Policy Committee issued the recommended statement on May 4, 2010.
"To ensure the free and open discussion of ideas, students may not record classroom lectures,
discussion and/or activities without the advance written permission of the instructor,
and any such recording properly approved in advance can be used solely for the student's own private use."
