zap: Zap small values in k-forms and k-tensors

In stokes: The Exterior Calculus

Zap small values in k-forms and k-tensors

Description

Equivalent to zapsmall()

Usage

zap(X)
## S3 method for class 'kform'
zap(X)
## S3 method for class 'ktensor'
zap(X)

Arguments

X	Tensor or k-form to be zapped

Details

Given an object of class ktensor or kform, coefficients close to zero are ‘zapped’, i.e., replaced by ‘0’, using base::zapsmall().

Note, zap() actually changes the numeric value, it is not just a print method.

Value

Returns an object of the same class

Examples

S <- rform(7)
S == zap(S)  # should be TRUE because the coeffs are integers

(a <- rform())
(b <- rform()*1e-11)
a+b
zap(a+b)
