Functions

func ReadCSV

func ReadCSV(filename string) ([][]string, error)

ReadCSV reads all the data from csv file

func ReadCSVAsFloat

func ReadCSVAsFloat(filename string) ([][]float64, error)

ReadCSVAsFloat returns the values of csv as floats TODO runtime for very large csv file ???

Types

type Set

type Set map[interface{}]bool

Set represents a set data type

func NewSet

func NewSet(values ...interface{}) Set

NewSet create a new set from values

Example

package main

import (
	"fmt"

	"github.com/Duncodes/mathlib"
)

func main() {
	set := mathlib.NewSet(1, 2, 3, 3, 4)

	fmt.Println(set)

}
