Go Numeric

Go Package for Numerical Calculations & Statistics

0. Notation

• Vector is just []float64
• Matrix is just [][]float64

For example

package main

import (
    "github.com/Axect/Numeric/array"
    "github.com/Axect/Numeric/stats"
)

func main() {
    A := array.Create(1, 1, 100) // [1, 2, 3, 4, ... , 100]
    m := stats.Mean(A) // Mean
    v := stats.Var(A) // Variance
    
    B := array.Create(-100, 1, -1)
    array.Write([]Vector{A, B}, "test.csv") // Write to csvfile
}

1. Array

Array has some vector operations.

• Sub
• Add
• Mul
• Inner
• AddConst (Vector, float64)
• SubConst
• DivisionConst
• Float2Int ([]float64 -> []int64)
• Write ([]Vector -> csv)

2. Stats
