Homework:   The table below gives the textbook homework.   Textbook homework should be placed in the drop box on the 6th floor of APM  outside room 6307 by 5pm on the Thursday due date. Late homework will not be accepted.  Note that on the day before a midterm exam, the drop box will be emptied promptly at 5pm. All problems should be handed in, but we can only grade a selection. Solutions will be posted after the homework is due. The lowest homework score will be dropped.  To best learn the material, attempt the homework alone before collaborating or seeking help.

Matlab Homework:   There are eight Matlab assignments. One assignment is due every Monday before 2pm, starting on Monday 4/14. Completed assignments should be placed in the drop box on the 6th floor of APM.   You can get help with the Matlab assignment during the Tuesday Matlab session. You can also work on your Matlab assignment on your own. Check APM B349A Lab hours, and CLICS Lab hours. UCSD extension students taking the class can set up a computer account with Academic Computing Services (ACS) in APM 1313 on weekdays from 9:00 a.m.-4:30 p.m.. Students wishing to print from the Lab laser printers should set up a laser printing account online or by going to ACS.

Oasis Workshops for 20F : Are run on Wednesdays 4-6pm.

Exams: Bring your photo ID to the final exam. No calculators, notes, or books are allowed during the exam, and cell phones must be turned off.
Midterm 1 Stats: high 100%, low 22%, median 74%, mean 73.2%, SD 15%.

Prerequisites: MATH 20C

Grading: Matlab homework: 10%, Textbook homework: 10%,   2 midterm exams: 15% each,   final exam: 50%. (The lowest homework score will not be counted. Missed exams will count zero.)

Other interesting texts (not required): The higher level course MATH 102 uses Strang, Linear Algebra and Its Applications. Lots of resources for learning linear algebra can be found at Strang's MIT website.

Syllabus: Matrix algebra, solution of systems of linear equations by Gaussian elimination, determinants. Linear and affine subspaces, bases of Euclidean spaces. Eigenvalues and eigenvectors, quadratic forms, orthogonal matrices, diagonalization of symmetric matrices. Applications. Computing symbolic and graphical solutions using Matlab.
