CommandWindowOutput - Text produced by execution of task object's function

Description

CommandWindowOutput contains the text produced during the execution of a task object's Function property that would normally be printed to the MATLAB Command Window.

For example, if the function specified in the Function property makes calls to the disp command, the output that would normally be printed to the Command Window on the worker is captured in the CommandWindowOutput property.

Whether to store the CommandWindowOutput is specified using the CaptureCommandWindowOutput property. The CaptureCommandWindowOutput property by default is logical 0 to save network bandwidth in situations when the CommandWindowOutput is not needed.

Characteristics

Usage	Task object
Read-only	Always
Data type	String

Values

Before a task is evaluated, the default value of CommandWindowOutput is an empty string.

Examples

Get the Command Window output from all tasks in a job.

jm = findResource('scheduler','type','jobmanager', ...
          'name','MyJobManager','LookupURL','JobMgrHost');
j = createJob(jm);
createTask(j, @myfun, 1, {x});
createTask(j, @myfun, 1, {x});
.
.
alltasks = get(j, 'Tasks')
set(alltasks, 'CaptureCommandWindowOutput', true)
submit(j)
outputmessages = get(alltasks, 'CommandWindowOutput')
