The definition of Matrix Addition is adding one matrix by another matrix is obtained by just adding the corresponding entries of the matrices. In this tutorial, I am giving a matrix addition example using the PHP program.
The Below is an Example of Matrix Addition for Two Matrices
Suppose there is a matrix: a b
c d
There is another matrix: e f
g h
Now the addition of two matrices will be: a+e b+f
c+g d+h
Here is a PHP Program Example for the Implementation of Matrix Addition
<html>
<body>
<?php
echo "<b>The First matrix is given below:-</b>"."<br>";
$a=array(array());// First two dimensional array declaration
$b=array(array());//Second two dimensional array declaration
$c=array(array());//Third two dimensional array declaration
$rows=4;
$cols=4;
$m=1;
$n=1;
for($i=0;$i<$rows;$i=$i+1)
{
for($j=0;$j<$cols;$j=$j+1)
{
$a[$i][$j]=$m;
echo $a[$i][$j]." ";
$m=$m+1;
}
echo "<br>";
}
echo "<b>The second matrix is given below:-</b><br>";
for($i=0;$i<$rows;$i=$i+1)
{
for($j=0;$j<$cols;$j=$j+1)
{
$b[$i][$j]=$n;
echo $b[$i][$j]." ";
$n=$n*1;
}
echo "<br>";
}
echo "<b>The Final matrix is given below:-</b>"."<br>";
for($i=0;$i<$rows;$i=$i+1)
{
for($j=0;$j<$cols;$j=$j+1)
{
$c[$i][$j]=$a[$i][$j]+$b[$i][$j];
echo $c[$i][$j]." ";
}
echo "<br>";
}
?>
</body>
</html>
Output:
The First matrix is given below:-
1 2 3 4
5 6 7 8
9 10 11 12
13 14 15 16
The second matrix is given below:-
1 1 1 1
1 1 1 1
1 1 1 1
1 1 1 1
The Final matrix is given below:-
2 3 4 5
6 7 8 9
10 11 12 13
14 15 16 17
Here firstly we have created two matrices and displayed, then we have performed the addition of two matrices using the statement here $c[$i][$j]=$a[$i][$j]+$b[$i][$j] and finally we have displayed the resultant matrix.
