21-124 Modeling with Differential Equations Course Information: Section A Section B Section C Tuesday Tuesday Tuesday 9:30AM - 10:20AM 10:30AM - 11:20PM 11:30PM - 12:20PM Wean 5202 Wean 5202 Wean 5202 This is the course web page of 21-124. It exists to teach you to use the course software (Matlab, Dfield, and Pplane) and as a source of homework assignments, handouts and announcements. There is of course no substitute for attending the lectures. Please be aware that the CMU computing services only makes Matlab available on its Unix and Linux machines and when completing the following exercises you should be using machines of this type.
