Lapack::solveLinearEquation
(PECL lapack >= 0.1.0)
Lapack::solveLinearEquation — Solve a system of linear equations
Description
public static array Lapack::solveLinearEquation
( array
$a
, array $b
)This function computes the solution to the system of linear equations with a square matrix A and multiple right-hand sides B. Solves A * X = B for multiple B.
Parameters
-
a -
Square matrix of linear equations
-
b -
Right hand side to be solved for
Return Values
Matrix X
Examples
Example #1 Using Lapack::singularValues():
<?php
$a = array(
array( 6.80, -6.05, -0.45, 8.32, -9.67 ),
array(-2.11, -3.30, 2.58, 2.71, -5.14 ),
array( 5.66, 5.36, -2.70, 4.35, -7.26 ),
array( 5.97, -4.44, 0.27, -7.17, 6.08 ),
array( 8.23, 1.08, 9.04, 2.14, -6.87 ),
);
$b = array(
array( 4.02, -1.56, 9.81 ),
array( 6.19, 4.00, -4.09 ),
array( -8.22, -8.67, -4.57 ),
array( -7.57, 1.75, -8.61 ),
array( -3.03, 2.86, 8.99 ),
);
$result = Lapack::solveLinearEquation($a, $b);
?>
