Method Details

getEigenvalues

public static Matrix getEigenvalues(int n,
 double[] matrixData)

Returns the eigenvalues of a matrix. * Since eigenvalues can be complex, this returns an n x 2 Matrix where Column 0 is the Real part and Column 1 is the Imaginary part.

Parameters:

n - The dimension of the square matrix (n x n).

matrixData - The flat 1D array of the matrix data.

Returns:

A Matrix object of size n x 2.

getEigenvectors

public static Matrix getEigenvectors(int n,
 double[] matrixData)

Returns the eigenvectors of a matrix as a square Matrix. * This method is "Turbo" optimized because it computes eigenvalues once and passes them directly to the vector solver, avoiding the expensive QR algorithm repetition. * @param n The dimension of the square matrix (n x n).

Parameters:

matrixData - The flat 1D array of the matrix data.

Returns:

A Matrix object of size n x n where columns are eigenvectors.
