<p>I definitely understand nothing about what this all is supposed to do. At 1st glance: are you sure about calling </p>
<c>
&F0($t1,@c);
...
&F0(($t2+$step/2),( @c + (&k1($t2)/2)));
</c>
<p>? What (how many) arguments do you think <c>F0</c> receives in each case? </p>
<p></p>
<p>Further, <c>k2_1</c> calls <c>k1</c>. Just for sake of symmetry, I wonder if it should have been <c>k1_1</c>. Have you tested/debugged each subroutine/section, so they work as expected, instead of typing this huge and complex code to observe final results? And I suspect other monks' advice about code and PBP will follow.</p>
