Problem 6: Cholesky dempositions Grading criteria: correctness of explanations and code 6a. In your words, explain what the Cholesky decomposition of a matrix is, for which matrices it is defined, and why it is useful in numerical linear algebra. In t 1 6b. Use Sage's cholesky function to compute the Cholesky decomposition of the matrix 3-1-13-2 -1 6 5 1 2 M-1 5 6 13 -2 2 3 6 Type Markdown and LaTeX: 2 6c. Repeat the computation using numpy. In t 1 6d. Repeat the computation using Octave. You may either switch to the Octave kernel or call Octave directly from Sage In 6e. Repeat the computation using Julia. You will need to switch to the Julia kernel for this. In [ ] Problem 6: Cholesky dempositions Grading criteria: correctness of explanations and code 6a.
