In wrathematics/pbdDMAT: 'pbdR' Distributed Matrix Methods
chol2inv R Documentation
Inverse from Choleski (or QR) Decomposition
Description
qr() takes the QR decomposition.
Usage
## S4 method for signature 'ddmatrix'
chol2inv(x, size = NCOL(x))
Arguments
x
numeric distributed matrices for
size
number of columns of x containing the Choleski factorization.
Details
The function returns the inverse of a choleski factored matrix, or the
inverse of crossprod(x) if qr.R(qr(x)) is passed.
Value
A numeric distributed matrix.
Methods
- list("signature(x = \"ddmatrix\")")
- list("signature(x = \"ANY\")")
