collapse_matrix: Collapse the matrices of a matlist object
Description
This function is called by collapse_omega() and collapse_sigma() to
convert multiple matrix blocks into a single matrix block. This "collapsing"
of the matrix list is irreversible.
Usage
collapse_matrix(x, range = NULL, name = NULL)
Arguments
x
an object that inherits from matlist; this object is most
frequently extracted from a model object using omat() or smat() for
OMEGA and SIGMA, respectively
range
numeric vector of length 2 specifying the range of matrices
to collapse in case there are more than 2. The second element may be NA
to indicate the length of the list of matrices.
name
a new name for the collapsed matrix; note that this is the
matrix name, not the labels which alias ETA(n) or EPS(n); specifying a
name will only alter how this matrix is potentially updated in the future
Value
An update matlist object (either omegalist or sigmalist).
