linalg_matrix_power: Computes the 'n'-th power of a square matrix for an integer...

Description Usage Arguments Details See Also Examples

View source: R/linalg.R

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

Arguments

A

(Tensor): tensor of shape (*, m, m) where * is zero or more batch dimensions.

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).
