substituteParameters: Assign values to the parameters of a 'symbolicQspray'

In symbolicQspray: Multivariate Polynomials with Symbolic Parameters in their Coefficients

Assign values to the parameters of a 'symbolicQspray'

Description

Substitutes some values to the parameters of a symbolicQspray polynomial.

Usage

substituteParameters(Qspray, values)

Arguments

Qspray	a symbolicQspray object
values	vector of values to be substituted to the parameters; these values must be coercible to bigq numbers

Value

A qspray object.

See Also

Use changeParameters to apply a transformation of the parameters. Use substituteVariables to substitute some values to the variables.

Examples

library(symbolicQspray)
f <- function(a1, a2, X, Y) {
  (a1 + 2)*X^2*Y + (a2/(a1^2+a2))*X*Y
}
Qspray <- f(qlone(1), qlone(2), Qlone(1), Qlone(2))
a <- c(2, "2/3")
( qspray <- substituteParameters(Qspray, values = a) )
a <- gmp::as.bigq(a)
qspray == f(a[1], a[2], qlone(1), qlone(2)) ## should be TRUE
