Direct Access
The basic method to access a matrix element is by directly referencing its row and column indexes. This method is best used when you know the exact position of the element you want to access.
PHP
<?php $matrix = [ [1, 2, 3], [4, 5, 6], [7, 8, 9] ]; // Accessing the element at // row 2, column 3 $rowIndex = 1; $colIndex = 2; echo "Element at row 2, column 3: " . $matrix[$rowIndex][$colIndex]; ?> |
Output
Element at row 2, column 3: 6
