Behavior

y = (lower ≤ u ≤ upper), with independently configurable open endpoints. The worked example connects this operation to signals in Lemonergy Studio.

Connected concepts

Limits and interpretation

  • Shapes and element types are explicit. Values must be finite; automatic reshaping and unit conversion are not performed.

Reference basis

This software operation and its numerical conventions are defined by the public contract and worked example; no external research result is claimed.

Implementation sources

This reference follows the public interface and locally verified numerical checks for an upcoming release.
