Limitations
• Only real number matrices are currently supported (complex matrices not yet supported)
• For eigenvalues near zero, results may differ from those generated by numpy.linalg.eig

Disclaimer
• While every effort has been made to ensure accurate results, no guarantees can be made. Please use the results at your own discretion.
