Class LogMatrixDeterminant<T>

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.core.LogMatrixDeterminant<T>

Type Parameters:

T - data type for sign() output

All Implemented Interfaces:

Op

@Operator
public final class LogMatrixDeterminant<T>
extends PrimitiveOp

Computes the sign and the log of the absolute value of the determinant of

one or more square matrices.

The input is a tensor of shape `[N, M, M]` whose inner-most 2 dimensions form square matrices. The outputs are two tensors containing the signs and absolute values of the log determinants for all N input submatrices `[..., :, :]` such that the determinant = sign*exp(log_abs_determinant). The log_abs_determinant is computed as det(P)*sum(log(diag(LU))) where LU is the LU decomposition of the input and P is the corresponding permutation matrix.
