Split EFT coefficient vector into components

Source: R/morpho_eft.R
eft_split.Rd

Separate a flattened EFT coefficient vector into its An, Bn, Cn, Dn components.

Usage

eft_split(x)

Arguments

x

Numeric vector of EFT coefficients (length must be divisible by 4).

Value

List with four elements:

  • an: An coefficients (x-axis cosine terms)

  • bn: Bn coefficients (x-axis sine terms)

  • cn: Cn coefficients (y-axis cosine terms)

  • dn: Dn coefficients (y-axis sine terms)
