Detect increase

Reports whether the input increased since its previous sample.

Behavior

y[k] = (u[k] > u[k−1]). The worked example connects this operation to signals in Lemonergy Studio.

Original Lemonergy interface view. Lines identify ports; they are not a completed simulation circuit.

Ports and observed outputs
Name	Direction	Unit	Meaning
`in0`	input	1	Value; real scalar.
`out0`	output	1	Detected; bool scalar.

Defaults are initial model values. Select values for your own model and operating conditions.

Configuration fields
Parameter	Unit	Default	Meaning and limits
Sample period `sampleTimeS`	s	0.1	Exact sample grid period. Elapsed-time integration begins after initialization. Minimum 1e-06
Previous input at initialization `tables[0]`	1	[1]	Configured coefficients or initial values in column-major order.

Value = 2. Detected at 0 s = 1.

Numerical checks for the bundled synthetic example
Output	Time (s)	Expected value	Unit	Absolute tolerance
Detected `out0`	0	`1`	1	1e-08

11 actual recorded samples. Lines are visual guides between samples. Synthetic example, not measured cell data.

Reports whether the input increased since its previous sample.

Detect increase: y[k] = (u[k] > u[k−1]). The worked example connects this operation to signals in Lemonergy Studio.
- Use the block reference for settings and connections.
- Implementation tested locally; public release pending.

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

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

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