Array step

Changes an entire signal from its before value to its after value at an exact time.

Behavior

y(t) = before, t < change time; after, t ≥ change time. The worked example connects this operation to signals in Lemonergy Studio.

Connected concepts

Limits and interpretation

  • Before and after arrays must have exactly the same shape and element type.
  • 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.
