| linalg_matrix_power {torch} | R Documentation |
Computes the n-th power of a square matrix for an integer n.
Description
Supports input of float, double, cfloat and cdouble dtypes.
Also supports batches of matrices, and if A is a batch of matrices then
the output has the same batch dimensions.
Usage
linalg_matrix_power(A, n)
Arguments
A |
(Tensor): tensor of shape |
n |
(int): the exponent. |
Details
If n=0, it returns the identity matrix (or batch) of the same shape
as A. If n is negative, it returns the inverse of each matrix
(if invertible) raised to the power of abs(n).
See Also
linalg_solve() computes A$inverse() %*% B with a
numerically stable algorithm.
