T.matrices: List of T Matrices

Description Usage Arguments Details Value Note Author(s) References See Also Examples

Description

This function constructs a list of lists. The number of components in the high level list is n. Each of the n components is also a list. Each sub-list has n components each of which is an order n square matrix.

Usage

1

Arguments

n

a positive integer value for the order of the matrices

Details

Let {{\bf{E}}_{i,j}}\;i = 1, … ,n\;;\;j = 1, … ,n be a representative order n matrix created with function E.matrices. The order n matrix {{\bf{T}}_{i,j}} is defined as follows {{\bf{T}}_{i,j}} = ≤ft\{ {\begin{array}{*{20}{c}} {{{\bf{E}}_{i,j}}}&{i = j}\\ {{{\bf{E}}_{i,j}} + {{\bf{E}}_{j,i}}}&{i \ne j} \end{array}} \right.

Value

A list of n components.

1

A list of n components

2

A list of n components

...

n

A list of n components

Each component j of sublist i is a matrix {\bf{T}}_{i,j}

Note

The argument n must be an integer value greater than or equal to 2.
