Np

Description


Lite, Fast & Memory Efficient Mathematical PHP library for scientific computing

Np(numphp) is a library that provides objects for computing large sets of numbers in PHP.

Installation

Install Np into your project with Composer:

$ composer require ghostjat/np

##Sample Code

require __DIR__ . '/../vendor/autoload.php';
use Np\matrix;

$ta = matrix::randn(1000, 1000);    
$tb = matrix::randn(1000, 1000); // to generate random 2d matrix
$ta->dot($tb);                  // do a dot operation on given matrix
$ta->getMemory();              // get memory use
$ta->time();                  // get time
