Method Python MATLAB Description set_axis(cfg) arr.set_axis(cfg) — cfg is va.axis(...) or None arr.set_axis(cfg) — cfg is varray.axis(...) or [] In-place mutation: add, replace, or remove axis config. Reinitializes sideband arrays with defaults when adding/replacing. axis_config arr.axis_config (property) → axis or None arr.axis_config() (method) → axis or [] Returns the array's axis configuration, or nothing if no axis. has_axis arr.has_axis() → bool arr.hasAxis() → logical Returns True/true if the array has an axis configuration. Packed bytes arr.bytes (property) → uint8 ndarray arr.bytes (property) → uint8 column Axis-packed beat stream when axis is configured. Data-only bytes otherwise.
