constant(values:rowMajor:)

Returns a rank 2 tensor from an array of arrays.

Declaration

func constant(values: Array<Array<Float>>, rowMajor: Bool = false) -> BNNSGraph.Builder.Tensor<Float>

Discussion

The following code shows how to use this function to multiply two 2x2 matrices:

   let xValues = [[1, 2],
                  [3, 4]] as [[Float]]
   let yValues = [[5, 6],
                  [7, 8]] as [[Float]]

   let context = try BNNSGraph.makeContext {
       builder in

       let x = builder.constant(values: xValues)
       let y = builder.constant(values: yValues)

       let z = x.matmul(other: y)

       return [z] // On return, `z` equals `[19.0, 22.0, 43.0, 50.0]`.
   }
