In MESS: Miscellaneous Esoteric Statistical Scripts
sinv R Documentation
Invert a symmetric positive-definite matrix
Description
Inverts a symmetric positive-definite matrix without requiring the Matrix package.
Usage
sinv(obj)
Arguments
obj
The symmetric positive-definite matrix
Details
This function does no error checking and it is up to the user to ensure that the input is indeed symmetric, positive-definite, and a matrix.
Value
A matrix of the same size as the input object
Author(s)
Claus Ekstrom, claus@rprimer.dk.
Examples
m <- matrix(c(1, 0, .5, .5, 0, 1, .5, .5, .5, .5, 1, .5, .5, .5, .5, 1), 4)
