basis B and determine the matrix of the transformation with respect to B. 3) Perp(2,1,—2) b) reﬂagyg) 2. Let V be an n dimensional vector space and deﬁne the linear operator L : V ——> V
by L07) : 27. Prove that [L]B : I for any basis B of V. 3. Let V be an n dimensional vector space with basis B and let S be the vector space
of all linear operators L : V ——> V. Deﬁne T : S ——> M(n, n) by T(L) : [L]B.
Prove that T is a linear mapping. Use MATLAB to complete the following questions. You do not need to submit a printout of your work. Simply use MATLAB to solve the problems,
and submit written answers to the questions along with the rest of your assignment. ' For questions that involve a set of vectors, enter each vector separately, giving it a name
(e.g., 51, S2, s3) and then construct any required matrices from these vectors
(e. g., A : [51 S2 53]). This will make it easier for you to work with the various elements. Matrix Representation of a Linear Mapping Let L : R6 —> R6 be the linear mapping L[(a1, (12, 0,3, (14, a5, (16)] = (3a1 — 2% + 5613 + 3a4 + 2% + 2%,
4611 + 5G4 + 3615 — 5616, 5612 + 3% + 2a4 + 3% — 2a6, 5a1 + 5a2 — 4a3 — 504 — a5, 5611 —' 303 + 3615, a1 + 2G2 + a3 + 2614 + a5 ‘l" 2615) (a) Find A, the matrix representation of the linear mapping L, with respect to the basis, 8, where
B :{ (17070307071))(1>0a170a170)7(—17~170707—17~1)> (07 07 _1) _17 03 0)) (07 27 —2) 2) —2> 0)) (1) 2707 1) 27 }
