How to pass a 2 dimensional array as a function argument in Go? -

so want able pass matrix function in argument in golang. different size each time - e.g., 4x4 matrix, 3x2 matrix, etc. if try running test code below against source code error message like:

how pass 2 dimensional array function? i'm new go , come dynamic language background (python, ruby).

cannot use mat[:][:] (type [][3]int) type [][]int in argument zeroreplacematrix 

source code

func replacematrix(mat [][]int, rows, cols, a, b int) {  } 

test code

func testreplacematrix(t *testing.t) {     var mat [3][3]int     //some code     got := replacematrix(mat[:][:], 3, 3, 0, 1) } 

the easiest way use slices. unlike arrays passed reference,not value. example:

package main  import "fmt"  type matrix [][]float64 func main() {     onematrix := matrix{{1, 2}, {2, 3}}     twomatrix := matrix{{1, 2,3}, {2, 3,4}, {5, 6,7}}     print (onematrix)     print (twomatrix)  } func print(x matrix) {     _, := range x {         _, j := range {             fmt.printf("%f ", j)         }         fmt.println()     } }
