在Golang中随机生成矩阵(Randomly generating a matrix in Golang)

I'm currently writing a program and I want to randomly generate a matrix.

Currently I'm pre-setting the values in it as follows:

    m1 := [3][3]int{
    [3]int{1, 1, 1},
    [3]int{4, 1, 7},
    [3]int{1, 65, 1},
}

However I want the values inputted to be randomly generated in a range from 1-100.

import "math/rand"

I am importing the above library and trying to utilise it.

I have attempted to get this working however can't seem to make any headway.

    m1 := [3][3]int{
    [3]int{rand.Intn, 1, 1},
    [3]int{4, 1, 7},
    [3]int{1, 65, 1},
}

I have attempted to complete it with the above solution to make the first number random however I get the following error.

cannot use rand.Intn (type func(int) int) as type int in array or slice literal

Any help greatly appreciated.
