SparseMatrixMatMul

public final class SparseMatrixMatMul

Matrix-multiplies a sparse matrix with a dense matrix.

Returns a dense matrix. For inputs A and B, where A is CSR and B is dense; this op returns a dense C;

If transpose_output is false, returns:

C = A . B

If transpose_output is `true`, returns:

C = transpose(A . B) = transpose(B) . transpose(A)

where the transposition is performed along the two innermost (matrix) dimensions.

If conjugate_output is `true`, returns:

C = conjugate(A . B) = conjugate(A) . conjugate(B)

If both conjugate_output and transpose_output are `true`, returns:

C = conjugate(transpose(A . B)) = conjugate(transpose(B)) .
                                     conjugate(transpose(A))

Public Methods

public static SparseMatrixMatMul.Options adjointA (Boolean adjointA)

Parameters

adjointA	Indicates whether `a` should be conjugate-transposed.

public static SparseMatrixMatMul.Options adjointB (Boolean adjointB)

Parameters

adjointB	Indicates whether `b` should be conjugate-transposed.

public Output<T> asOutput ()

Returns the symbolic handle of the 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.

public static SparseMatrixMatMul.Options conjugateOutput (Boolean conjugateOutput)

Parameters

conjugateOutput	Conjugates the product of `a` and `b`.

public static SparseMatrixMatMul<T> create (Scope scope, Operand<?> a, Operand<T> b, Options... options)

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

Parameters

scope	current scope
a	A CSRSparseMatrix.
b	A dense tensor.
options	carries optional attributes values

Returns

a new instance of SparseMatrixMatMul

public Output<T> output ()

A dense output tensor.

Parameters

transposeB	Indicates whether `b` should be transposed.

public static SparseMatrixMatMul.Options transposeOutput (Boolean transposeOutput)

Parameters

transposeOutput	Transposes the product of `a` and `b`.
