coeffs: Extract and manipulate coefficients

In stokes: The Exterior Calculus

Extract and manipulate coefficients

Description

Extract and manipulate coefficients of ktensor and kform objects; this using the methods of the spray package.

Functions as.spray() and nterms() are imoported from spray.

Details

To see the coefficients of a kform or ktensor object, use coeffs(), which returns a disord object (this is actually spray::coeffs()). Replacement methods also use the methods of the spray package.

Examples

(a <- kform_general(5,2,1:10))
coeffs(a) # a disord object
coeffs(a)[coeffs(a)%%2==1] <- 100  # replace every odd coeff with 100
a

coeffs(a*0)
