set.daeTolerance {dae} | R Documentation |
A function that sets the values such that, in dae functions,
values less than it are considered to be zero. The values are stored
in a vector
named daeTolerance
in the daeEnv
environment. The vector
is of length two and, initially, both
values are set to .Machine$double.eps ^ 0.5
(about 1.5E-08).
One value is named element.tol
and is used for elements of
matrices; the second is named element.eigen
and is used for
eigenvalues and quantities based on them, such as efficiency factors.
