How to multiply complex matrices Golang gonum/mat

Question

I have:

    dataA := []complex128{
        1 + 2i, 3 + 4i,
        5 + 6i, 7 + 8i,
    }
    A := mat.NewCDense(2, 2, dataA)
    dataB := []complex128{
        9 + 10i, 11 + 12i,
        13 + 14i, 15 + 16i,
    }
    B := mat.NewCDense(2, 2, dataB)

    var C mat.CDense

    C.Mul(A, B)

it doesn't work

type mat.CDense has no field or method Mul)

Answer 1

I was able to multiply complex matrices as follows:

package main

import (
     "fmt"
     "gonum.org/v1/gonum/blas"
     "gonum.org/v1/gonum/blas/cblas64"
)

func main() {
     a := cblas64.General{
         Rows:   2,
         Cols:   2,
         Stride: 2,
         Data:   []complex64{1 + 2i, 3 + 4i, 5 + 6i, 7 + 8i},
     }

     b := cblas64.General{
         Rows:   2,
         Cols:   1,
         Stride: 1,
         Data:   []complex64{9 + 10i, 11 + 12i},
     }

     c := cblas64.General{
         Rows:   2,
         Cols:   1,
         Stride: 1,
         Data:   make([]complex64, 2),
     }


     cblas64.Gemm(blas.NoTrans, blas.NoTrans, 1, a, b, 0, c)

     for i := 0; i < c.Rows; i++ {
         fmt.Printf("%v\n", c.Data[i])
     }

}
