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