When it comes to code Mathcad 11 and earlier to Smath,
Most of the time I hit the wall ! "scalar" has two meanings:
A gem is a stone, but few stones are "gems" ... agree ?
It concerns interpreting non-interpretable error messages
otherwise than from educated inside knowledge.

Worth meditate the nuance: vector/scalar

Revisit the late Smath "Fourier Quantum CoC" [Samples].
