Background: piecewise-linear continuous functions $f(x_k)=y_k$ with fixed set of knots $x_k$ with restrictions on the angles between adjacent segments.
The translator who dealt with my paper, introduced terminology that I don't like, i.e. (my variants are on the left):
- knots -> nodes
- adjacent segments -> neighboring links
- segment -> link
- polylines -> broken lines
Which one is better? How would you call piecewise-linear function, its segments, its knots? What are the most common namings for these?
NB: That's more about piecewise-linear functions than about polylines in the geometrical sense.
