Need some explanation in Blasius and Falkner-Skan.jl #6
Description
in Blasius and Falkner-Skan.jl
f = (u)->(2.0*D^3*u + 3*u*D^2*u)
df = (u)->(2.0*D^3 + u*D^2 + D^2*u)
Shouldn't it be
df = (u)->(6.0*D^2 + D^2*u + 2*u*D*u)
Other thing is,
global u -= [B; df(u)]\[u(0.);u'(0.);u'(rightendpoint(d))-1.;f(u)]
What is happening in this line of code?
