Factored Inverses of Real Symmetric Matrices,applying a single-vector Lanczos procedure to the inverse of an associated matrix B ≡ PCP., where C = S0*A + SHIFT*I. The scalars S0 and SHIFT are specified by the user, selected in such a way that the resulting matrix C (or B) has a reasonable numerical condition. The permutation matrix P is chosen不在灌木丛中 发表于 2025-3-27 08:05:08

Real Rectangular Matrices, rectangular matrices, using a single-vector Lanczos procedure. For a given real rectangular ℓ × n matrix A, these codes compute nonnegative scalars . and corresponding real vectors x ≠ 0 and y ≠ 0 such that . Every real rectangular ℓxn matrix, where ℓ . n, has a singular value decomposition, . whertic-douloureux 发表于 2025-3-27 17:08:53
Nondefective Complex Symmetric Matrices, using a single-vector Lanczos procedure. For a given nondefective, complex symmetric matrix A, these codes compute complex scalars À and corresponding complex vectors x ≠ 0 such that . . A complex nxn matrix A ≡ (a.), 1 ≤ i,j ≤ n, is complex symmetric if and only if for every i and j, a. = a.. A coarthrodesis 发表于 2025-3-27 18:43:43
