Sum or mean of elements

Reduces an array to its sum or arithmetic mean.

Behavior

sum = Σᵢ uᵢ; mean = (Σᵢ uᵢ)/N. 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	Values; real 3 array.
`out0`	output	1	Result; real scalar.

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

Configuration fields
Parameter	Unit	Default	Meaning and limits
Reduction `params[0]`	1	1	0 sum; 1 arithmetic mean.

Values = [1,2,3]. Result at 0 s = 2.

Numerical checks for the bundled synthetic example
Output	Time (s)	Expected value	Unit	Absolute tolerance
Result `out0`	0	`2`	1	1e-08

Sum or mean of elements

Sum or mean of elements: 2 — at 0 s

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

Reduces an array to its sum or arithmetic mean.

Sum or mean of elements: sum = Σᵢ uᵢ; mean = (Σᵢ uᵢ)/N. 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.
