What are the limitations of using PHP for matrix operations compared to other languages like Java?

PHP lacks built-in support for matrix operations compared to languages like Java, making it less efficient for performing complex mathematical calculations on matrices. To overcome this limitation, you can use external libraries like PHPMatrix, which provide functions for matrix operations in PHP.

// Example of using PHPMatrix library for matrix operations
require_once 'PHPMatrix.php';

// Create a new matrix
$matrix = new Matrix([
    [1, 2],
    [3, 4]
]);

// Perform matrix multiplication
$result = $matrix->multiply($matrix);

// Display the result
echo $result;
