ndarray-linear-solve

Solves a system of linear equations, similar to MATLAB's backslash operator, but not yet as sophisticated. (But maybe it will be someday soon! Pull requests welcome!)



example

`` js
var solve = require('ndarray-linear-solve');
var show = require('ndarray-show');
var ndarray = require('ndarray');

var A = ndarray([ 2, 1, -1, -3, -1, 2, -2, 1, 2 ], [ 3, 3 ], [ 1, 3 ]);
var B = ndarray([ 8, -11, -3 ])
var X = ndarray(new Float64Array(3))
var r = solve(X, A, B)
console.log('input:\n' + show(A), '\n');
if (r) {
console.log('solution:\n' + show(X));
} else {
console.log('matrix is singular')
}
`

output:

`
input:
2.000 1.000 -1.000
-3.000 -1.000 2.000
-2.000 1.000 2.000

solution:
2.000 3.000 -1.000

`

methods

` js
var solve = require('ndarray-linear-solve')
`

var solution = solve(X, A, B)


Solves the linear system, AX = B for X

* X is a vector into which the solution is written
* A is a matrix encoded as an ndarray
* B is a vector, encoded as an ndarray

Returns true if the matrix has a solution, otherwise false.

install

With npm do:

`
npm install ndarray-linear-solve
