Splet07. jun. 2024 · I am trying to invert a matrix using svd and \ and comparing the result with inv (). For this matrix: Theme Copy A = [ 2 4 6; 8 5 7 ; 0 3 1] I did the svd decomposition as follows: Theme Copy [U,S,V] = svd (A); And, I believe the inverse of A can be expressed as : So, I tried it by writing the code below: Theme Copy disp ('inverse with svd:') Splet4. First we will assume that M is a real matrix. In the complex case, the geometry of the SVD is a little harder to visualize because taking inner products also requires conjugation. Also, let us define the SVD as follows: if M is m × n, then the SVD is given by. M = U Σ V ∗, where U, V have orthonormal columns, Σ is diagonal with non ...
