Matrix transposition

Transposing a matrix flips a matrix diagonally, swapping rows and column indices. The following image shows an example transposition of a matrix:

We can represent a matrix transposition in Go using the following code:

package mainimport (    "fmt"    "gonum.org/v1/gonum/mat")func main() {    a := mat.NewDense(3, 3, []float64{5, 3, 10, 1, 6, 4, 8, 7, 2})    matrixPrint(a)    matrixPrint(a.T())}func matrixPrint(m mat.Matrix) {    formattedMatrix := mat.Formatted(m, mat.Prefix(""), mat.Squeeze())    fmt.Printf("%v\n", formattedMatrix)}

The result of this matrix transposition can be seen in the following image:

In the preceding output, we can ...
