Assign Matrix to a pdMat Object

Description

The positive-definite matrix represented by object is replaced by value. If the original matrix had row and/or column names, the corresponding names for value can either be NULL, or a permutation of the original names.

Usage

## S3 method for class 'pdMat':
matrix(object) <- value

Arguments

object an object inheriting from class pdMat, representing a positive definite matrix.
value a matrix with the new values to be assigned to the positive-definite matrix represented by object. Must have the same dimensions as as.matrix(object).

Value

a pdMat object similar to object, but with its coefficients modified to produce the matrix in value.
