freealg.FreeForm.eigvalsh

FreeForm.eigvalsh(size=None, seed=None, **kwargs)

Estimate the eigenvalues.

This function estimates the eigenvalues of the freeform matrix or a larger matrix containing it using free decompression.

Parameters:

sizeint, default=None

The size of the matrix containing \(\mathbf{A}\) to estimate eigenvalues of. If None, returns estimates of the eigenvalues of \(\mathbf{A}\) itself.

seedint, default=None

The seed for the Quasi-Monte Carlo sampler.

Returns:

eigsnumpy.array
