Method invert

static member invert: Tensor<'T> -> Tensor<'T>

(Batch) inverts a matrix.

Declaration
static member invert: a:Tensor<'T> -> Tensor<'T>
Parameters
Type Name Description
Tensor<'T> a

The input matrix or tensor to this operation.
Returns
Type Description
Tensor<'T>

A new matrix or tensor containing the result of this operation.
Remarks

If a is a square matrix, its inverse is computed. The result is a matrix.

If a is a tensor of shape [b_1; ...; b_n; i; i], the inverse of all square matrices consisting of the last two dimensions of the tensor are computed. The result is a tensor of same shape.

If the matrix is not invertible a SingularMatrixException is raised. Use static member pseudoInvert: Tensor<'T> * 'T option -> Tensor<'T> for such matrices instead.

Examples
 let a = HostTensor.ofList [[1.0; 2.0]
                            [3.0; 4.0]]
 let c = Tensor.invert a // c = [[-2.0; 1.0]    
                         //      [1.5; -0.5]]
Exceptions
Type Condition
SingularMatrixException

Raised when the matrix is not invertible.
