JavaScript Wrapper for eigenvalues and eigenvectors using LAPACK.
The left and right eigenvectors are normalize meaning that the largest components are made real. This is done using the Lapack dgeev method.
npm install matrix-eig
var matrixEig = require('matrix-eig');
var matrix = [[0, 1],[-2, -3]]
var result = matrixEig.eig(matrix);
console.log(result.eigenvalues.real);
// Float64Array [ -1, -2 ]
console.log(result.eigenvalues.imaginary);
// Float64Array [ 0, 0 ]
console.log(result.eigenvectors.left);
// Float64Array [
// 0.8944271909999159,
// 0.4472135954999579,
// 0.7071067811865475,
// 0.7071067811865475 ]
console.log(result.eigenvectors.right);
// Float64Array [
// 0.7071067811865475,
// -0.7071067811865475,
// -0.4472135954999579,
