Unformatted text preview: of a matrix, A, type inv(A) 2.2 Eigenstuﬀ and Determinants These problems will add up to 25 points 2.2.1 Determinants Summer Test problems 3a and 3b. Make up 2x2 and 3x3 matrices and check with Matlab. To ﬁnd the determinant of a matrix, A, type det(A). 2.2.2 2x2 Eigenvalues and Eigenvectors For the following problems, ﬁnd the eigenvalues and eigenvectors: • summer test problem 3c (last page) • pg.324: 3-6, 8, 11 • make up you own and test with Matlab using [V,D]=eig(A,’nobalance’). The eigen-vectors are the columns of V and the eigenvalues are along the diagonal of D. **remember that your eigenvectors may be oﬀ by a factor on both numbers; this is OK. 2.2.3 3x3 Eigenvalues Find the eigenvalues for the following problems: • summer test problem 3d (2nd to last page) • pg.324: 19, 22, 24, 27-30 (just eigenvalues) 2...
