torch_inverse.RdInverse
Arguments
- self
(Tensor) the input tensor of size \((*, n, n)\) where
*is zero or more batch dimensions
Note
Irrespective of the original strides, the returned tensors will be
transposed, i.e. with strides like `input.contiguous().transpose(-2, -1).stride()`inverse(input, out=NULL) -> Tensor
Takes the inverse of the square matrix input. input can be batches
of 2D square tensors, in which case this function would return a tensor composed of
individual inverses.
Examples
if (torch_is_installed()) {
if (FALSE) {
x = torch_rand(c(4, 4))
y = torch_inverse(x)
z = torch_mm(x, y)
z
torch_max(torch_abs(z - torch_eye(4))) # Max non-zero
# Batched inverse example
x = torch_randn(c(2, 3, 4, 4))
y = torch_inverse(x)
z = torch_matmul(x, y)
torch_max(torch_abs(z - torch_eye(4)$expand_as(x))) # Max non-zero
}
