A_inv = np.linalg.inv(A) x = np.dot(A_inv, y) print(x) [ 2.20833333 -2.58333333 -0.18333333] We can also get the L and U matrices used in the LU decomposition using the scipy package. TRY IT! Get the L and U for the above matrix A.
WebSince the inverse of a matrix is unique, then the matrix equation Ax = y can be solved by multiplying each side of the equation, on the left, by A − 1. This results in A − 1Ax = A − 1y → Ix = A − 1y → x = A − 1y, which gives the unique solution to the equation. If m > n, then there are more equations than unknowns. WebExpert Answer.
