Behavior

On reset, minimum = maximum = u; otherwise update the running extrema. The worked example connects this operation to signals in Lemonergy Studio.

Limits and interpretation

  • Per-element running extrema with Boolean reset, evaluated at configured sample instants.
  • 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.
