MatrixLogarithm
Stay organized with collections
Save and categorize content based on your preferences.
Computes the matrix logarithm of one or more square matrices:
\\(log(exp(A)) = A\\)
This op is only defined for complex matrices. If A is positive-definite and
real, then casting to a complex matrix, taking the logarithm and casting back
to a real matrix will give the correct result.
This function computes the matrix logarithm using the Schur-Parlett algorithm.
Details of the algorithm can be found in Section 11.6.2 of:
Nicholas J. Higham, Functions of Matrices: Theory and Computation, SIAM 2008.
ISBN 978-0-898716-46-7.
The input is a tensor of shape `[..., M, M]` whose inner-most 2 dimensions
form square matrices. The output is a tensor of the same shape as the input
containing the exponential for all input submatrices `[..., :, :]`.

()
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.
Factory method to create a class wrapping a new MatrixLogarithm operation.
Parameters
