DAE initial value problem - Predefined cases

Select the test problem please:

	chemical reaction	I will use own initial values no yes c0, T0, tend: 10,90,4
	van der Pol equation and limit case	ε = I will use own initial values no yes y0, (z0), tend: 0.5,5.0 Important: for ε =0 you must define only c0 and tend and otherwise you must define y0, z0, tend
	pendulum, transformed to index 1	I will use own initial values no yes θ ,α ,tend: 3.5,-1.0,5.0

Select two components of y for plotting: index1=index2=1 is allowed

index1 =		Important index1 from 1,...,n !
index2 =		Important: index2 from 1,...,n !

Please specify: precision wanted
tol = Important: this is relative precision, 0 < tol < 1 !
The absolute error bound is tol × smally :
smally = Important: smally > 0 !

Specify the maximum stepsize allowed:
hmax=
Important: hmax > 0 . Too large hmax will be reset automatically .

Please select the initial stepsize hstart:
hstart = Important: 0 < hstart <= hmax !

Please specify the maximal order allowed:
maxorder=
Important: maxorder <= 5.

Should the algebraic components be included in the precision test?

	yes
	no	y-status is defined internally

How many subintervals should be treated separately?
1 means direct integration from t₀ to t_end. 1 <= num <= 100.
