Package org.tensorflow.op.linalg

Class TriangularSolve<T>

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.linalg.TriangularSolve<T>

Type Parameters:

T - data type for output() output

All Implemented Interfaces:

Op, Operand<T>

@Operator(group="linalg")
public final class TriangularSolve<T>
extends PrimitiveOp
implements Operand<T>

Solves systems of linear equations with upper or lower triangular matrices by

backsubstitution.

`matrix` is a tensor of shape `[..., M, M]` whose inner-most 2 dimensions form square matrices. If `lower` is `True` then the strictly upper triangular part of each inner-most matrix is assumed to be zero and not accessed. If `lower` is False then the strictly lower triangular part of each inner-most matrix is assumed to be zero and not accessed. `rhs` is a tensor of shape `[..., M, K]`.

The output is a tensor of shape `[..., M, K]`. If `adjoint` is `True` then the innermost matrices in `output` satisfy matrix equations `matrix[..., :, :] * output[..., :, :] = rhs[..., :, :]`. If `adjoint` is `False` then the strictly then the innermost matrices in `output` satisfy matrix equations `adjoint(matrix[..., i, k]) * output[..., k, j] = rhs[..., i, j]`.

                                            TriangularSolve.Options... options)

Factory method to create a class to wrap a new TriangularSolve operation to the graph.

Parameters:

scope - current graph scope

matrix - Shape is `[..., M, M]`.

rhs - Shape is `[..., M, K]`.

options - carries optional attributes values

Returns:

a new instance of TriangularSolve

lower

public static TriangularSolve.Options lower(java.lang.Boolean lower)

Parameters:

lower - Boolean indicating whether the innermost matrices in `matrix` are lower or upper triangular.

adjoint

public static TriangularSolve.Options adjoint(java.lang.Boolean adjoint)

Parameters:

adjoint - Boolean indicating whether to solve with `matrix` or its (block-wise) adjoint.

output

public Output<T> output()

Shape is `[..., M, K]`.

asOutput

public Output<T> asOutput()

Description copied from interface: Operand

Returns the symbolic handle of a tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

Specified by:
