# graphBuilderTensor(_:) Returns a tensor for the specified BNNS Graph builder. ``` func graphBuilderTensor(_ builder: BNNSGraph.Builder) -> BNNSGraph.Builder.Tensor ``` ## Discussion The following code shows how to use this function to register a tensor from an array. ``` let x = [1, 2, 3, 4] as [Float] let y = [5, 6, 7, 8] as [Float] let context = try BNNSGraph.makeContext { builder in let x = lhs.graphBuilderTensor(builder) let z = x.matmul(transpose: true, other: y) return [z] // On return, `z[0]` equals `70`. } ``` --- Copyright © 2026 Apple Inc.
