Change of basis matrix formula

WebWell there we can just multiply. Remember w is just equal to the change of basis matrix times w's coordinates with respect to the basis B. So w is going to be equal to the change of basis matrix, which is just 1, 3, 2, 1, times the coordinates of w with respect to B times 1, 1. Which is equal to 1 times 1 plus 2 times 1 is 3. Webi for the matrix multiplication above. Orthonormal Change of Basis and Diagonal Matrices. Suppose Dis a diagonal matrix, and we use an orthogonal matrix P to change to a new basis. Then the matrix Mof Din the new basis is: M= PDP 1 = PDPT: Now we calculate the transpose of M. MT = (PDPT)T = (PT)TDTPT = PDPT = M So we see the matrix PDPT …
