WebFeb 8, 2024 · numerical_derivative = (erfcx (x+1.0e-6)-erfcx (x))*1e6; plot (x,analytical_derivative,x,numerical_derivative) So my guess is that the derivative of erfcx is erfcx' (x) = -2/sqrt (pi) + 2*x*erfcx (x) (and you can easily deduce this result by differentiating exp (x^2)*erfcx (x) using the product rule).
