# init(alpha:transposesX:transposesY:)

Creates a batched matrix multiplication descriptor with the alpha value and transpose options you specify.

## Declaration

```swift
convenience init?(alpha: Float, transposesX: Bool, transposesY: Bool)
```

## Parameters

- `alpha`: A scalar value you specify to scale the left-hand side, C = alpha x A x B.
- `transposesX`: A Boolean that specifies whether you choose to transpose the last two dimensions of x.
- `transposesY`: A Boolean that specifies whether you choose to transpose the last two dimensions of y.
