Matrix_power

Usage

torch_matrix_power(self, n)

Arguments

self: (Tensor) the input tensor.
n: (int) the power to raise the matrix to

matrix_power(input, n) -> Tensor

Returns the matrix raised to the power n for square matrices. For batch of matrices, each individual matrix is raised to the power n.

If n is negative, then the inverse of the matrix (if invertible) is raised to the power n. For a batch of matrices, the batched inverse (if invertible) is raised to the power n. If n is 0, then an identity matrix is returned.

Examples

if (torch_is_installed()) {

a = torch_randn(c(2, 2, 2))
a
torch_matrix_power(a, 3)
