zero: Zero tensors and zero forms

Description

Correct idiom for generating zero \(k\)-tensors and \(k\)-forms

Usage

zeroform(n)
zerotensor(n)

Arguments

n

Arity of the \(k\)-form or \(k\)-tensor

Examples

# NOT RUN {
as.ktensor(1+diag(5)) + zerotensor(5)
as.kform(matrix(1:6,2,3)) + zeroform(3)

# }
# NOT RUN {
as.ktensor(1+diag(5)) +  as.ktensor(rep(1,5),0)   # fails
as.kform(matrix(1:6,2,3)) + as.kform(1:3,0)   # also fails
# }
# NOT RUN {
# }
