tf.linalg.slogdet
Computes the sign and the log of the absolute value of the determinant of
tf.linalg.slogdet( input, name=None )
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.
