Find Matrix Addition
In the following example, we will add the two given matrices (two-dimensional arrays).
Example
PHP Compiler
<?php
$arr1 = array(
array(1, 1, 1),
array(1, 1, 1),
array(1, 1, 1),
);
$arr2 = array(
array(2, 2, 2),
array(2, 2, 2),
array(2, 2, 2),
);
echo "Matrix A (3 x 3): <br>";
for($i=0; $i<3; $i++)
{
for($j=0; $j<3; $j++)
echo $arr1[$i][$j] . " ";
echo "<br>";
}
echo "<br>Matrix B (3 x 3): <br>";
for($i=0; $i<3; $i++)
{
for($j=0; $j<3; $j++)
echo $arr2[$i][$j] . " ";
echo "<br>";
}
echo "<br>Matrix Additon (A + B): <br>";
for($i=0; $i<3; $i++)
{
for($j=0; $j<3; $j++)
{
$arr3[$i][$j] = $arr1[$i][$j] + $arr2[$i][$j];
echo $arr3[$i][$j] . " ";
}
echo "<br>";
}
?>
Output
Matrix A (3 x 3):
1 1 1
1 1 1
1 1 1
Matrix B (3 x 3):
2 2 2
2 2 2
2 2 2
Matrix Additon (A + B):
3 3 3
3 3 3
3 3 3
