WebbThe inverse of a matrix is shown by A -1. Matrices inverse is calculated by using the following formula: A -1 = (1/ A ) (Adj A) where A is the determinant of the matrix A and A ≠ 0. Adj A is the adjoint of the given matrix A. The inverse of a 2 × 2 matrix A = [a11 a12 a21 a22] is calculated by: A -1 = 1 a11a22 − a12a21( a22 − a12 − a21 a11) WebbThe standard format of an idempotent matrix is A = (a b c d) ( a b c d), and bc = a - a 2, d = 1 - a Let us take a = 4, d = 1 - 4 = -3 bc = 4 - 4 2 = 4 - 16 = -12 Here we can take b = 6, c = -2 A = [ 4 6 −2 −3] [ 4 6 − 2 − 3] Therefore the idempotent matrix is [ 4 6 −2 −3] [ 4 6 − 2 − 3].
