dRatioOfQsprays: Partial differentiation

In ratioOfQsprays: Fractions of Multivariate Polynomials with Rational Coefficients

Partial differentiation

Description

Partial differentiation of a ratioOfQsprays polynomial.

Usage

dRatioOfQsprays(roq, orders)

Arguments

roq	object of class ratioOfQsprays
orders	integer vector, the orders of the differentiation; e.g. c(2, 0, 1) means that you differentiate two times with respect to x, you do not differentiate with respect to y, and you differentiate one time with respect to z

Value

A ratioOfQsprays object.

Examples

library(ratioOfQsprays)
x <- qlone(1)
y <- qlone(2)
roq <- (x + 2*y  + 3*x*y) / (x + 1)
dRatioOfQsprays(roq, c(1, 1))
derivRatioOfQsprays(derivRatioOfQsprays(roq, 1), 2)
