  • numpy. linalg. pinv — NumPy v2. 3 Manual
    linalg pinv (a, rcond=None, hermitian=False, *, rtol=<no value>) [source] # Compute the (Moore-Penrose) pseudo-inverse of a matrix Calculate the generalized inverse of a matrix using its singular-value decomposition (SVD) and including all large singular values
  • When will numpy. linalg. inv () and numpy. linalg. pinv () give . . .
    for the equation Ax = b, let A = USV t, i need to calculate inverse of (S T@S) I noticecd that using np linalg inv () and np linalg pinv () gives extremely different results np allclose () infact returns false
  • Linear algebra — NumPy v2. 3 Manual
    Return the least-squares solution to a linear matrix equation linalg inv (a) Compute the inverse of a matrix linalg pinv (a[, rcond, hermitian, rtol]) Compute the (Moore-Penrose) pseudo-inverse of a matrix linalg tensorinv (a[, ind]) Compute the 'inverse' of an N-dimensional array
  • Pinv not inverting my complex matrix entirely correct
    I am inverting a non-square complex matrix Upon inverting I find myself with absolute values that are correct but the real or the complex (always one is incorrect but never both) values are negative when they need to be postive and vice-versa
