Hi Hötzi,
And on basis of this story we will define Hötzi's universal law of BE:
ElMaestro is always right1.
By the way, since you are a speed devotee:
Footnote 1:
Except when he isn't. Which also happens. With regrettable frequency...
❝ You have a point. IMHO, this question should be answered: yes!
And on basis of this story we will define Hötzi's universal law of BE:
ElMaestro is always right1.
By the way, since you are a speed devotee:
FindCritCV.Sec=function(Pwr.T, GMR, Nps, Is.St2=1, d=.00001, iniCV)
##the secant method has really nasty properties if the ini value is a little off.
{
CV1=iniCV
CV2=CV1*1.05
y2=1
while (abs(y2)>d)
{
y1=Power.calc(Nps, GMR, CV1, Is.St2)-Pwr.T
y2=Power.calc(Nps, GMR, CV2, Is.St2)-Pwr.T
CV3= CV2-y2*(CV2-CV1)/(y2-y1)
CV1=CV2
CV2=CV3
}
return(0.5*(CV1+CV2)) ##or play around
}
(...)
for (Nps in 6:length(vecCritCVs))
{
if (Nps==6) iniCV=min(0.709*GMR-0.552, 0.709/GMR -0.552)
else iniCV=vecCritCVs[Nps-1]
vecCritCVs[Nps]<<-FindCritCV.Sec(0.8, GMR, Nps, 1, 1e-10, iniCV)
}
(...)
