Nd solve stiffness test nonstifftest method option

Tutorial 4 steps, run in order in one session. Every step was executed against the engine and the output below is what it produced.

Step 1

a = {{0., 1.}, {2623.532160943381, -69.56342161343568}};

No output - this step sets something up for the next one.

Step 2

{Abs[First[Eigenvalues[a]]], Norm[a, 1], Norm[a, Infinity]}

Output

{96.69535685979352, 2623.532160943381, 2693.0955825568167}

Step 3

Options[NDSolve`SubspaceIteration]

Output

{}

Step 4

Options[NDSolve`KrylovIteration]

Output

{}
