DGLFIT - Predefined case: exponential decay/growth

Select your settings for the optimizer (DONLP2)

	optimization parameter standard
	my own settings: desired final precision in parameters in [1.0e-7,1.0e-2]    epsx= allowed intermediate deviation for constraints >= 1.0e-4    tau0= desired maximal final violation of constraints in [1.0e-8,1.0e-2] delmin= amount of additional optimizer output: 0=none, 1=one line/step, 2=detailed, 3=very detailed iolevel=

Select your settings for the problem and the integrator

predefined: y' = -2y+1, y(0)=4 , tol=1.0e-10, smally=1, maxord=5, hmax=0.05, hstart=1.0e-3

my own settings: The maximal order allowed: maxord = Important: maxord <= 5. Precision wanted    tol = Important: this is relative precision, 1.0e-14 <= tol <= 1.0e-2 ! The absolute error bound is tol × smally : smally = Important: smally > 0 ! The maximum stepsize allowed:  hmax = Important: hmax > 0 . Too large hmax will be reset automatically to 0.1 The initial stepsize : hstart = Important: 0 < hstart <= hmax ! Specify the three problem parameters p1, p2, y0 here as three numbers in a list: -2,1,4, Important : p1 <> 0 !

Specify the amount of artificial data perturbation here in [0,1]: 0 means ''no''
and 1 means ''100 percent'' error relative to the absolutely largest true y-value.
       u =

Specify the number of artificial ''measurement'' points here in the range 3 to 100:
