m2c

go for 2x2 complex matrices

Description

Complex matrices 2x2 (a.k.a. m2c) are a wonderful land to explore. They are matrices of the form

     | a  b |
     | c  d |

Where a, b, c, d are complex numbers. I found Golang as the perfect language to implement them since it has complex128 data type, yeah!

Examples

First of all import m2c.

import "github.com/fibo/m2c"

Create an identity matrix

var id = m2c.Matrix{1, 0, 0, 1}
fmt.Println(id) // {(1+0i) (0+0i) (0+0i) (1+0i)}

Multiply two matrices.

var a = m2c.Matrix{1, 0, 0, 1}
var b = m2c.Matrix{1, 1 + 1i, 0, 1 - 1i}

var c = m2c.Mul(a, b)
fmt.Println(c) // {(1+0i) (1+1i) (1+1i) (1-1i)}

Invert a matrix.

var d = m2c.Matrix{2i, 0, 0, 1}

var invD, err = m2c.Inv(d)

if err != nil {
	log.Fatal(err)
}

fmt.Println(invD) // {(0-0.5i) (-0+0i) (-0+0i) (1+0i)}
