Course number: | MA-UY 4423 |

Semester: | Spring 2016 |

Time & Location: | Tues & Thurs, 2:00pm - 3:30pm in JABS 673 |

Instructor: | Mike O'Neil (oneil@cims.nyu.edu) |

Office hours: | Tues & Thurs, 3:30pm - 5:00pm in RH 321F |

This course will serve as an introduction to the topic of numerial analysis for those students interested in gaining some knowledge of the computational aspects of mathematics on modern day computers. This course is intended for students that have completed Calculus II, Ordinary Differential Equations, and (maybe) have some programming experience. Topics covered in this class will include: floating-point arithmetic, numerical integration and differentiation, interpolation, numerical linear algebra, orthogonal polynomials, and solution of ODEs. Time permitting, algorithms used in Monte Carlo methods and optimization will be covered. Programming assignments will be in Matlab.

The course text will be
Greenbaum and Chartier,
*Numerical Methods:
Design, Analysis, and Computer Implementation of
Algorithms*.
Notes covering additional topics in numerical linear algebra will
be provided. Course homework will partially be drawn
from the textbook.

Other textbooks that might serve as useful supplements are:

- Burden and Faires,
*Numerical Analysis* - Suli and Mayers,
*An Introduction to Numerical Analysis* - Stoer and Bulirsch,
*Introduction to Numerical Analysis*(more advanced)

The grades in the course will be determined based on homework, a midterm exam, and a final exam. Details to follow.
