Hello Everybody,
Thanks to all of you for these extremely interesting postings. I am barely able to fully understand them in depth... I need a bit of time to study them thoroughly. Programming is like making music, and this is a symphony!!
Once again, thanks for all these good suggestions.
Marco

Also some improvements in efficiency so that runtime is now approx. -25%. Marco, your Line Intersection is a piece of gold for Engineering works. 1. Trifolium 2. Dragilev implicit solve 3. Focus [suggested as next exercise] Zillions thanks ... Jean Maths InterX.r1 (2) Trifolium Copy.sm (104kb) downloaded 27 time(s).

This means that this syntax of stack/augment is about 40 times faster then without it. Thank you! Edited by user 21 February 2018 23:36:46(UTC)
