The native finite differences has three [3] exceptional virtues:
1. very accurate/fast
2. independent of data spacing
3. largely insensitive to noisy data set.
The algo style takes any function or otherwise infinitesimal.
The scalar spline offers quick command line evaluation.
Up to this point of the document, no restriction ...
Great utility ... Scientific/Engineering ... gorgeous Smath !!!

1. ProductLog(x) coded compatible canvas plot
2. Incompatible Σalgo(lo,mesh,hi,∫)
3. Given native FD [Finite Differences]
...applicable to other "reluctant" functions.
