RepeatAlongAxis

Repeat the data along the given axis.

This node basically repeats n copies of the data along the desired axis. One of the most common use cases is to extend an array to match the size of another array to then perform an elementwise operation between the two, such as addition. Version 1.1.2

Ports/Properties

data

Data to process.

  • verbose name: Data
  • default value: None
  • port type: DataPort
  • value type: AnyNumeric (can be None)
  • data direction: INOUT

axis

Axis along which to repeat. Select the space axis for channels, instance axis for trials or segments, time for the number of time points, feature for the number of features in the stream, etc. Note that, when you specify the axis positionally (by using an integer), out-of-bounds indices (before or after the valid dimensions) will be treated as a missing axis that will by default be inserted right before or after the existing axes.

  • verbose name: Axis
  • default value: instance
  • port type: ComboPort
  • value type: str (can be None)

create_axis

Under what conditions to create the desired axis in the data. If this is set to no, then the operation is skipped for any streams that do not have the axis in question. If this is set to if-missing, then the axis will be created for any streams that do not have it (but excluding marker streams). If this is set to always, then the axis in question will always be created (again, not in marker streams), even if it already exists.

  • verbose name: Create Axis
  • default value: if-missing
  • port type: EnumPort
  • value type: str (can be None)

num_repeats

Number of repetitions. The data will be repeated this many times along the given axis. The repeat operation is a multiplication of the data along the axis, so if the number of repeats is 1, the data will be passed through unchanged.

  • verbose name: Num Repeats
  • default value: 1
  • port type: IntPort
  • value type: int (can be None)

verbose

Print warnings for edge cases.

  • verbose name: Verbose
  • default value: True
  • port type: BoolPort
  • value type: bool (can be None)

set_breakpoint

Set a breakpoint on this node. If this is enabled, your debugger (if one is attached) will trigger a breakpoint.

  • verbose name: Set Breakpoint (Debug Only)
  • default value: False
  • port type: BoolPort
  • value type: bool (can be None)

metadata

User-definable meta-data associated with the node. Usually reserved for technical purposes.

  • verbose name: Metadata
  • default value: {}
  • port type: DictPort
  • value type: dict (can be None)
