## Declaration

```swift
func matrixMultiplication(primary primaryTensor: MPSGraphTensor, secondary secondaryTensor: MPSGraphTensor, name: String?) -> MPSGraphTensor
```

## Parameters

- `primaryTensor`: The left-hand side tensor.
- `secondaryTensor`: The right-hand side tensor.
- `name`: The name for the operation.

## Return Value

Return Value A valid tensor containing the product of the input matrices.
