Create a matrix of coefficients using an arbitrary function

Produces an object that may be used in place of a matrix in the creation of arguments to spec_rescomp().

rescomp_coefs_matrix_custom(func, nrow, ncol)

Arguments

func

A function that takes params (a list of parameters) and returns a matrix.

nrow

The number of rows in the matrix returned by func.

ncol

The number of columns in the matrix returned by func.

Value

S3 object of class rescomp_coefs_matrix.

Examples

# Matrix with one time-varying coefficient
rescomp_coefs_matrix_custom(
  function(params) {
    matrix(c(0.2, 0.3, 0.4, params$fourth_coeff), nrow = 2, ncol = 2)
  },
  nrow = 2, ncol = 2
)
