# inverse(input:name:)

Computes the inverse of an input tensor.

```
func inverse(input inputTensor: MPSGraphTensor, name: String?) -> MPSGraphTensor
```

## Parameters

`inputTensor`

The input tensor.

`name`

The name for the operation.

## Return Value

A valid [`MPSGraphTensor`](/documentation/MetalPerformanceShadersGraph/MPSGraphTensor) object containing the inverse of the input tensor.

## Discussion

The framework computes the inverse of a square matrix by calling LU decomposition and LU solver.
All dimensions after the first 2 are treated as batch dimensions and the inverse for each batch is computed.
Results are undefined for ill conditioned matrices.
