LogMatrixDeterminant

public final class LogMatrixDeterminant

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 `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.
