Lecture Notes

MATLAB® software is required to run the .m files in this section. File decompression software, such as Winzip® or StuffIt®, is required to open the .zip files in this section.

13.811 is split into two segments: structural dynamics for the first half of the semester and acoustics for the second half. 

NOTE: Only the acoustics component is available on this site. The structural dynamics component has not yet been incorporated into OCW.
