class pySimBlocks.blocks.operators.demux.Demux(name: str, num_outputs: int = 2, sample_time: float | None = None)

Bases: Block

Vector split block (inverse of Mux).

Splits one input column vector of length n into p output segments. Segment sizes are distributed as evenly as possible: let q = n // p and m = n % p, then the first m outputs have size q+1 and the remaining p-m outputs have size q.

num_outputs

Number of output segments to produce.

direct_feedthrough = True

True if outputs depend directly on inputs.

initialize(t0: float) → None

Compute initial outputs, or set zero placeholders if input is unavailable.

Parameters:

t0 – Initial simulation time in seconds.

output_update(t: float, dt: float) → None

Split the input vector and write the segments to the output ports.

Parameters:

• t – Current simulation time in seconds.

• dt – Current time step in seconds.

Raises:

• RuntimeError – If input 'in' is not connected.

• ValueError – If input is not a column vector or has fewer elements than num_outputs.

state_update(t: float, dt: float) → None

No-op: Demux is a stateless block.

Parameters:

• t – Current simulation time in seconds.

• dt – Current time step in seconds.
