Introduction

This library provides a simple way to manipulate and perform calculations with complex numbers.

Installation

You can install this library via Composer

composer require alemian95/php-complex-numbers

Usage

Creating Complex Numbers

You can create a complex number using either Cartesian coordinates (real and imaginary parts) or polar coordinates (magnitude and argument)

use Alemian95\PhpComplexNumbers\Complex;

// Create a complex number using Cartesian coordinates
$complex1 = new Complex(3.0, 4.0);

// Create a complex number using polar coordinates
$complex2 = Complex::createFromPolar(5.0, 0.92729521800161); // Equivalent to (3, 4)

Basic Operations

You can perform basic arithmetic operations on complex numbers, such as addition, subtraction, multiplication, and division:

// Addition
$sum = $complex1->add($complex2);

// Subtraction
$diff = $complex1->sub($complex2);

// Multiplication
$product = $complex1->mul($complex2);

// Division
$quotient = $complex1->div($complex2);

Other operations

You can also perform other operations such as calculating the absolute value, argument, and conjugate of a complex number:

// Absolute value
$absoluteValue = $complex1->abs();

// Argument
$argument = $complex1->arg();

// Conjugate
$conjugate = $complex1->conjugate();
