Math 300: Mathematical Computing

Matlab Slices

  1. Make a matrix called A whose first row comprises the numbers 1, 2, 3, ..., 10; whose second row comprises 1, 3, 5, ..., 19; and whose third row is all ones.
  2. Let \(A_k\) denote the \(3\times3\) matrix whose first entry is \(A_{1,k}\) and whose lower-right corner element is \(A_{3,k+2}\), for \(k=1,2,\dots,8\). Find \(A_3\).
  3. Let \(x[1,1,1]^T\). What is \(A_5x?\)
  4. What is \(x^TA_6\)?
  5. What is the rank of A?

The "final exam" for this course will take place at 8:00 AM on Tuesday, 12 December. This will be an ordinary 50 minute test. It will be comprehensive, but weighted toward the latter half of the semester. As always, paper notes will be permitted, but no electronic devices will be allowed.

A Solution example is available for the quiz.

Assignment A is posted.
