Approximate equality of mvp objects

Two multivariate polynomials \(x,y\) are held to be approximately equal if the coefficients of \(x-y\) are small compared to the coefficients of \(x\) and \(y\) separately. The comparison all.equal() is dispatched to all_equal_mvp() which uses base::all.equal().

Usage

all_equal_mvp(target, current)

Arguments

target,current

Objects of class mvp

Examples

a <- rmvp()
a1 <- a + rmvp()/1e5
a2 <- a - rmvp()/1e5
all.equal(a1,a2)
#> [1] "Mean scaled difference: 6e-06"
