dQspray: Partial differentiation

In qspray: Multivariate Polynomials with Rational Coefficients

Partial differentiation

Description

Partial differentiation of a qspray polynomial.

Usage

dQspray(qspray, orders)

Arguments

qspray	object of class qspray
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 qspray object.

Examples

library(qspray)
x <- qlone(1)
y <- qlone(2)
qspray <- x + 2*y  + 3*x*y
dQspray(qspray, c(1, 1))
derivQspray(derivQspray(qspray, 1), 2)
