Web1x + 2y+3z = 5 2x + 3y + 1z = 6 3x + 7y + 2z = 8 This is written in matrix form: A*x = b, where x in this example is a vector of variables [x ; y ; z]. To solve for x, we premultiply both sides of the equation by the inverse of A: inv (A)*A*x = inv (A)*b, and since inv (A)*A = I, the identity matrix, x = inv (A)*b.

WebExample 2: Check if the inverse of the matrix $D = \left[\begin{array}{ccc} 2 & 0 \\ \\ 0 & 0 \end{array}\right] $ exists. Solution: As we can see, row 2 of matrix D is equal to 0, this implies the matrix is singular and hence, has a determinant equal to 0. Although, all non-diagonal elements of the matrix D are zero which implies it is a diagonal matrix. WebTo zero out the second row on the first column, you need to do: 4 (2) - 2 (4) = 0 And then the same thing to the second column, second row: 4 (2) - 2 (8) = -8 Therefore, the more generalized transformation is: 4 (c2) - 2 (c1) That makes sense, right?
