labProbe - Test to see if messages are ready to be received from other lab

Syntax

is_data_available = labProbe is_data_available = labProbe(source) is_data_available = labProbe('any',tag) is_data_available = labProbe(source,tag) [is_data_available, source, tag] = labProbe

Arguments

`source`	`labindex` of a particular lab from which to test for a message.
`tag`	Tag defined by the sending lab's `labSend` function to identify particular data.
`'``any``'`	String to indicate that all labs should be tested for a message.
`is_data_available`	Boolean indicating if a message is ready to be received.

Description

is_data_available = labProbe returns a logical value indicating whether any data is available for this lab to receive with the labReceive function.

is_data_available = labProbe(source) tests for a message only from the specified lab.

is_data_available = labProbe('any',tag) tests only for a message with the specified tag, from any lab.

is_data_available = labProbe(source,tag) tests for a message from the specified lab and tag.

[is_data_available, source, tag] = labProbe returns labindex and tag of ready messages. If no data is available, source and tag are returned as [].
