Brobdingagian matrix arithmetic

Description

Basic arithmetic for Brobdingnagian matrices

Usage

brobmat.mult(e1, e2)
brobmat.add(e1, e2)
brobmat.mult(e1, e2)
brobmat.power(e1, e2)
brobmat.inverse(e1)
brobmat.greater(e1, e2)
brobmat.equal(e1, e2)
getat(e1,e2)

Arguments

e1,e2

Arguments coerced to brobmat

Details

These functions are helper functions used by the brobmat Arith group and are not designed to be user-friendly. Function getat() is a helper function that sets attributes such as dimnames of returned values.

Value

Return a brobmat, or logical for the comparison operators.

Examples

a <- brobmat(1:54,6,9)
rownames(a) <- letters[1:6]
a + 1e30
a-a

b <- as.brobmat(matrix(rnorm(27),9,3))
colnames(b) <- month.abb[1:3]

a %*% b
