Golang : Gonum standard normal random numbers example


Tags : golang gonum standard-normal random

Putting this simple example here for my own future reference. Just another way of generating random numbers beside using math/rand.

In the code example below, we learn how to generate random numbers using the gonum.org/v1/gonum/stat/distuv package.

Here you go!


 package main

 import (
  "fmt"

  "gonum.org/v1/gonum/stat/distuv"
 )

 func main() {

  n := 1000 // number of simulations

  // Create a standard normal (mean = 0, stdev = 1)
  // https://docs.scipy.org/doc/numpy/reference/generated/numpy.random.standard_normal.html
  //dist := distuv.Normal{
  // Mu: 0, // Mean of the normal distribution
  // Sigma: 1, // Standard deviation of the normal distribution
  //}

  // use the defined variable
  dist := distuv.UnitNormal.

  z := make([]float64, n)

  // Generate some random numbers from standard normal distribution
  for i := range z {
 z[i] = dist.Rand()
  }

  fmt.Println(z)

 }
