The iterator yields :py:class:`asyncio.Future` which gets done whenever response arrives or error occurs. Parameters ---------- snmpDispatcher: :py:class:`~pysnmp.hlapi.v1arch.asyncore.SnmpDispatcher` Class instance representing asynio-based asynchronous event loop and associated state information. authData: :py:class:`~pysnmp.hlapi.v1arch.CommunityData` Class instance representing SNMPv1/v2c credentials. transportTarget: :py:class:`~pysnmp.hlapi.v1arch.asyncio.UdpTransportTarget` or :py:class:`~pysnmp.hlapi.v1arch.asyncio.Udp6TransportTarget` Class instance representing transport type along with SNMP peer address. notifyType : str Indicates type of notification to be sent. Recognized literal values are *trap* or *inform*. \*varBinds: :class:`tuple` of OID-value pairs or :py:class:`~pysnmp.smi.rfc1902.ObjectType` or :py:class:`~pysnmp.smi.rfc1902.NotificationType` One or more objects representing MIB variables to place into SNMP notification. It could be tuples of OID-values or :py:class:`~pysnmp.smi.rfc1902.ObjectType` class instances of :py:class:`~pysnmp.smi.rfc1902.NotificationType` objects. Besides user variable-bindings, SNMP Notification PDU requires at least two variable-bindings to be present: 0. SNMPv2-MIB::sysUpTime.0 = <agent uptime> 1. SNMPv2-SMI::snmpTrapOID.0 = <notification ID> When sending SNMPv1 TRAP, more variable-bindings could be present: 2. SNMP-COMMUNITY-MIB::snmpTrapAddress.0 = <agent-IP> 3. SNMP-COMMUNITY-MIB::snmpTrapCommunity.0 = <snmp-community-name> 4. SNMP-COMMUNITY-MIB::snmpTrapEnterprise.0 = <enterprise-OID> If user does not supply some or any of the above variable-bindings or if they are at the wrong positions, the system will add/reorder the missing ones automatically. On top of that, some notification types imply including some additional variable-bindings providing additional details on the event being reported. Therefore it is generally easier to use :py:class:`~pysnmp.smi.rfc1902.NotificationType` object which will help adding relevant variable-bindings. Other Parameters ---------------- \*\*options : Request options: * `lookupMib` - load MIB and resolve response MIB variables at the cost of slightly reduced performance. Default is `False`, unless :py:class:`~pysnmp.smi.rfc1902.ObjectType` or :py:class:`~pysnmp.smi.rfc1902.NotificationType` is present among `varBinds` in which case `lookupMib` gets automatically enabled. Yields ------ errorIndication: str True value indicates SNMP engine error. errorStatus: str True value indicates SNMP PDU error. errorIndex: int Non-zero value refers to `varBinds[errorIndex-1]` varBinds: tuple A sequence of OID-value pairs in form of base SNMP types (if `lookupMib` is `False`) or :py:class:`~pysnmp.smi.rfc1902.ObjectType` class instances (if `lookupMib` is `True`) representing MIB variables returned in SNMP response. Raises ------ PySnmpError Or its derivative indicating that an error occurred while performing SNMP operation.

As SciPy's ``scipy.io.loadmat`` function can handle the earlier formats, if this function cannot read the file, it will dispatch it onto the scipy function with all the calling arguments it uses passed on. This function is modelled after the SciPy one (arguments not specific to this package have the same names, etc.). Parameters ---------- file_name : str Name of the MAT file to read from. The '.mat' extension is added on automatically if not present if `appendmat` is set to ``True``. mdict : dict, optional The dictionary to insert read variables into appendmat : bool, optional Whether to append the '.mat' extension to `file_name` if it doesn't already end in it or not. variable_names: None or sequence, optional The variable names to read from the file. ``None`` selects all. marshaller_collection : MarshallerCollection, optional Collection of marshallers from disk to use.
