brobmat: Brobdingnagian matrices

In Brobdingnag: Very Large Numbers in R

Brobdingnagian matrices

Description

Basic matrix arithmetic for Brobdingnagian numbers. Matrix addition, multiplication extraction and replacement implemented but not the determinant or matrix inverse.

Usage

brobmat(..., positive)
newbrobmat(x,positive)
as.brobmat(x)
is.brobmat(x)
brobmat_to_brob(x)
diag(x,...)
## S3 method for class 'brobmat'
print(x,...)
t(x,...)

Arguments

x	Argument
...	Further arguments
positive	Logical, indicating whether an element is positive

Details

Basic arithmetic for Brobdingnagian matrices.

Function brobmat() is like brob() in that it interprets its first argument as the exponent (but creates a matrix). Function as.brobmat() coerces a numeric matrix to a brobmat.

Value

Generally return a brobmat or brob.
