Inverse
torch_inverse(self)
self | (Tensor) the input tensor of size \((*, n, n)\) where |
---|
Irrespective of the original strides, the returned tensors will be transposed, i.e. with strides like `input.contiguous().transpose(-2, -1).stride()`
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.
