check_eigen_decomposition {wISAM}

check_eigen_decomposition

Description

Grabbed from MASS. Useful to sparsify matrices when some eigenvalues are essentially zero.

Usage

check_eigen_decomposition(e, tol = 1e-06)

Arguments

e

the eigen decomposition to check

tol

the threshold below which a number is said to be effectively zero, defaults to 1e-6

Value

The eigen values with any values with absolute value less than tol zeroed.
