Svd

public final class Svd

Computes the singular value decompositions of one or more matrices.

Computes the SVD of each inner matrix in `input` such that `input[..., :, :] = u[..., :, :] * diag(s[..., :, :]) * transpose(v[..., :, :])`

# a is a tensor containing a batch of matrices.
 # s is a tensor of singular values for each matrix.
 # u is the tensor containing the left singular vectors for each matrix.
 # v is the tensor containing the right singular vectors for each matrix.
 s, u, v = svd(a)
 s, _, _ = svd(a, compute_uv=False)

Public Methods

public static Svd.Options computeUv (Boolean computeUv)

Parameters

computeUv	If true, left and right singular vectors will be computed and returned in `u` and `v`, respectively. If false, `u` and `v` are not set and should never referenced.

public static Svd<T> create (Scope scope, Operand<T> input, Options... options)

Factory method to create a class wrapping a new Svd operation.

Parameters

scope	current scope
input	A tensor of shape `[..., M, N]` whose inner-most 2 dimensions form matrices of size `[M, N]`. Let `P` be the minimum of `M` and `N`.
options	carries optional attributes values

Returns

• a new instance of Svd

public static Svd.Options fullMatrices (Boolean fullMatrices)

Parameters

fullMatrices	If true, compute full-sized `u` and `v`. If false (the default), compute only the leading `P` singular vectors. Ignored if `compute_uv` is `False`.

public Output<T> s ()

Singular values. Shape is `[..., P]`.

public Output<T> u ()

Left singular vectors. If `full_matrices` is `False` then shape is `[..., M, P]`; if `full_matrices` is `True` then shape is `[..., M, M]`. Undefined if `compute_uv` is `False`.

public Output<T> v ()

Left singular vectors. If `full_matrices` is `False` then shape is `[..., N, P]`. If `full_matrices` is `True` then shape is `[..., N, N]`. Undefined if `compute_uv` is false.
