print.stokes: Print methods for \(k\)-tensors and \(k\)-forms

Description

Print methods for objects with options for printing in matrix form or multivariate polynomial form

Usage

# S3 method for kform
print(x, ...)
# S3 method for ktensor
print(x, ...)

Value

Returns its argument invisibly.

Arguments

x

k-form or k-tensor

...

Details

The print method is designed to tell the user that an object is a tensor or a k-form. It prints a message to this effect (with special dispensation for zero tensors), then calls the spray print method.

kform(spray(kform_basis(4,2),1:6))  # runs out of symbols


options(kform_symbolic_print = "txyz")
kform(spray(kform_basis(4,2),1:6))  # standard notation
