Beam.naturalFrequenciesAndEigenvectors(n)

Computes first n natural frequncies and associated eigenvectors of beam

n : int

number of natural frequencies/eigenvectors to return. if n exceeds the total DOF of the structure then all natural frequencies are returned

freq : ndarray (Hz)

natural frequncies from lowest to highest. Size n except for case noted above.

vector : ndarray(ndarray)

vector[i] corresponds to freq[i]
