Vector selector

Selects a configured element from a real vector.

Behavior

The zero-based element index is checked against the fixed vector dimension before execution.

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

Ports and observed outputs
Name	Direction	Unit	Meaning
`vector`	input	1	Vector; real signal.
`element`	output	1	Element 1; real signal.

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

Configuration fields
Parameter	Unit	Default	Meaning and limits
Vector length `n`	1	3	Explicit n used by this worked model.
Selected zero-based index `index`	1	1	Explicit index used by this worked model.
Physical quantity `quantity`	1	dimensionless	Explicit quantity used by this worked model.

A = 1; B = 2; C = 3. Result at 1 s = 24.

Selects a configured element from a real vector.

Vector selector: The zero-based element index is checked against the fixed vector dimension before execution.
- Use the block reference for settings and connections.
- Implementation tested locally; public release pending.

The selected index is configured before the run; use other routing operations for dynamic selection.

This software operation is defined by its 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.
