RcppFaddeeva (version 0.2.2)

Faddeeva_w: Faddeeva family of error functions of the complex variable

Description

the Faddeeva function

Usage

Faddeeva_w(z, relerr = 0)
erfcx(z, relerr = 0)
erf(z, relerr = 0)
erfi(z, relerr = 0)
erfc(z, relerr = 0)
Dawson(z, relerr = 0)

Arguments

z

complex vector

relerr

double, requested error

Value

complex vector

Functions

• Faddeeva_w: compute w(z) = exp(-z^2) erfc(-iz)

• erfcx: compute erfcx(z) = exp(z^2) erfc(z)

• erf: compute erf(z)

• erfi: compute erfi(z) = -i erf(iz)

• erfc: compute erfc(z) = 1 - erf(z)

• Dawson: compute Dawson(z) = sqrt(pi)/2 * exp(-z^2) * erfi(z)

Examples

# NOT RUN {
Faddeeva_w(1:10 + 1i)
erfcx(1:10 + 1i)
erf(1:10 + 1i)
erfi(1:10 + 1i)
erfc(1:10 + 1i)
Dawson(1:10 + 1i)
# }
