ErrorIdentifier - Task error identifier

Description

If an error occurs during the task evaluation, ErrorIdentifier contains the identifier property of the MException thrown.

Characteristics

Usage	Task object
Read-only	Always
Data type	String

Values

ErrorIdentifier is empty before an attempt to run a task, and remains empty if the evaluation of a task function does not produce an error or if the error did not provide an identifier. ErrorIdentifier has the same value as the identifier property of the task's Error.

When using a job manager, ErrorIdentifier indicates if a worker has crashed during task execution, but when using a different scheduler ErrorIdentifier does not indicate a crash.

Examples

Error Identifier Retrieval

Retrieve the error identifier from a task object.

jm = findResource('scheduler','type','local');
j = createJob(jm);
a = [1 2 3 4]; % Note: matrix not square.
t = createTask(j, @inv, 1, {a});
submit(j)
waitForState(j)
e_id = get(t,'ErrorIdentifer')

e_id =
MATLAB:square
