(description "@code{PositiveFactorizations} is a package for computing a
|
||||||
|
positive definite matrix decomposition (factorization) from an arbitrary
|
||||||
|
symmetric input. The motivating application is optimization (Newton or
|
||||||
|
quasi-Newton methods), in which the canonical search direction -H/g (H being the
|
||||||
|
Hessian and g the gradient) may not be a descent direction if H is not positive
|
||||||
|
definite.")
