Cholesky-class {Matrix} | R Documentation |
The "Cholesky"
class is the class of Cholesky
decomposition of a positive-semidefinite, real matrices
Objects can be created by calls of the form new("Cholesky", ...)
or by calls of the form chol(pm)
where pm
inherits from
the "poMatrix"
class or as a side-effect of other functions
applied to "poMatrix"
objects.
