今天就跟大家聊聊有关怎么在PHP中利用数组实现矩阵数学运算,可能很多人都不太了解,为了让大家更加了解,小编给大家总结了以下内容,希望大家根据这篇文章可以有所收获。

矩阵运算就是对两个数据表进行某种数学运算,并得到另一个数据表.
下面的例子中我们创建了一个基本完整的矩阵运算函数库,以便用于矩阵操作的程序中.
';
// For each row in the matrix:
for ($r = 0; $r < $rows; $r++) {
// Begin the row:
echo '';
// For each column in this row
for ($c = 0; $c < $columns; $c++) {
// Echo the element:
echo "{$matrix[$r][$c]} ";
}
// End the row.
echo ' ';
}
// End the table.
echo "/n";
} else {
// It wasn't well formed:
return false;
}
}
// Let's do some testing. First prepare some formatting:
echo " /n";
// Now let's test element operations. We need identical sized matrices:
$m1 = array(
array(5, 3, 2),
array(3, 0, 4),
array(1, 5, 2),
);
$m2 = array(
array(4, 9, 5),
array(7, 5, 0),
array(2, 2, 8),
);
// Element addition should give us: 9 12 7
// 10 5 4
// 3 7 10
matrix_print(matrix_element_operation($m1, $m2, '+'));
// Element subtraction should give us: 1 -6 -3
// -4 -5 4
// -1 3 -6
matrix_print(matrix_element_operation($m1, $m2, '-'));
// Do a scalar multiplication on the 2nd matrix: 8 18 10
// 14 10 0
// 4 4 16
matrix_print(matrix_scalar_operation($m2, 2, '*'));
// Define some matrices for full matrix operations.
// Need to be complements of each other:
$m3 = array(
array(1, 3, 5),
array(-2, 5, 1),
);
$m4 = array(
array(1, 2),
array(-2, 8),
array(1, 1),
);
// Matrix multiplication gives: 0 31
// -11 37
matrix_print(matrix_operation($m3, $m4, '*'));
// Matrix addition gives: 9 20
// 4 15
matrix_print(matrix_operation($m3, $m4, '+'));
