ierfc(z) : sign definition
Function ierfc(z)
Wolfram Alpha defines it as z×erfc(z) - e^(-z²)/sqrt(pi) and calculates accordingly. At Wikipedia, French version, of Function d'erreur, section "Extensions", we find the reverse definition, ie: e^(-z²)/sqrt(pi) - z×erfc(z). Is there an "error" here? What is the most common convention or the "correct" definition ? Thanks for your answer. |
