GNU Octave
Scilab
Students have occasionally reported incompatibilities with Octave. I have not
received any complaints about Scilab.
You may use Python and NumPy for programming assignments if you want, but
you should make sure that you understand Matlab, since there may be problem
sets and exam questions that involve Matlab.

None.
Description
This course gives an introduction to theory, computational techniques, and
applications of linear algebra, probability and statistics. These three
areas of continuous mathematics are critical in many parts of computer
science, including machine learning, scientific computing, computer vision,
computational biology, computational finance,
natural language processing, and computer graphics.
The course will teach a specialized language for mathematical computation,
such as MATLAB, and will discuss how the language can be used for
computation and for graphical output. No prior knowledge of linear algebra,
probability, or statistics is assumed.

Students with Disabilities
Academic accommodations are available for students with disabilities.
Please contact the Moses Center for Students with Disabilities (2129984980
or mosescsd@nyu.edu) for further information. Students who are requesting
academic accommodations are advised to reach out to the Moses Center
as early as possible in the semester for assistance.
Cheating
You may discuss any of the assignments with your classmates (or anyone else)
but all work for all assignments must be
entirely your own. Any sharing or copying of assignments will be
considered cheating. By the rules of the Graduate School of Arts and Science,
I am required to report any incidents of cheating to the department.
My policy is that any incident of cheating will result in the
student getting a grade of F for the course.
The second incident, by GSAS rules, will result
in expulsion from the University.
