evalSymbolicQspray {symbolicQspray}

Evaluation of a 'symbolicQspray' polynomial

Description

Evaluates a symbolicQspray polynomial by substituting some values to the parameters (same as substituteParameters) or to the variables (same as substituteVariables) or both.

Usage

evalSymbolicQspray(Qspray, a = NULL, X = NULL)

Arguments

Qspray

a symbolicQspray object

a

vector of values to be substituted to the parameters; these values must be coercible to bigq numbers

X

vector of values to be substituted to the variables; these values must be coercible to bigq numbers

Value

If both a and X are NULL, this returns the input symbolicQspray object; otherwise, if a is not NULL, this returns a qspray object, and if X is not NULL, this returns a ratioOfQsprays object.

Examples

library(symbolicQspray)
a1 <- qlone(1); a2 <- qlone(2)
X1 <- Qlone(1); X2 <- Qlone(2); X3 <- Qlone(3)
( Qspray <- (a1 + 2)*X1^2*X2 + (a2/(a1^2+a2))*X1*X2*X3 )
a <- c(2, 3)
X <- c(4, 3, 2)
( qspray <- evalSymbolicQspray(Qspray, a = a) )
( rOQ <- evalSymbolicQspray(Qspray, X = X) )
evalSymbolicQspray(Qspray, a = a, X = X)
evalQspray(qspray, X)
evalRatioOfQsprays(rOQ, a)
