26_MatrixArray: Matrix Arrays

In vectools: Advanced Vector Toolkit

Description

A MatrixArray is a subclass of ObjectArray.
These represent a (currently one dimensional) array of matrices.

The package provides binary operators to apply matrix multiplication over the entire array.

NOTE:
INTERNAL STRUCTURE OF OBJECTS IS SUBJECT TO CHANGE.
DO NOT USE SLOTS, DIRECTLY.

Usage

MatrixArray (n, ..., NR, NC, conform=TRUE, default.value=ZERO)
as.MatrixArray (v, ..., n, NR, NC, conform=TRUE)

Arguments

n	Integer, the length Currently, the top-level object is constrained to one dimension.
v	A suitable object. Such as a list of matrices.
NR, NC	Currently, these need to be set to NA.
conform	Logical, if true, submatrices are required to have conformable dimensions.
default.value	The default value.
...	Ignored.

Value

A MatrixArray object.
