' - - File: XVIbRoots

' An example of a nonlinear BVP with multiple roots. Refer to File XVIb for its use.
' This scan will help identify the approximate location of the roots -- roots that are the
' slope estimates using the shooting method.

'  Given:  X"(t) - 1.5  X'(t)^2 = 0
F{t,x,y} = y
G{t,x,y} = 1.5  x^2

to = 0: xo = 4 : tb = 1: xb =1 : n = 200 : a1 = -50 :  a2 = -2

BVP[F, G, {to,xo,tb,xb} { a1, a2 } {1, .001, -9}]   ' <-- minus to compute a set of X'{..}.

'  NOTE: A 9 indicates number of point to compute a plot to seek zero crossings.
