message

MESSAGE is a suppressible version of fprintf that functions similarly to WARNING.

MESSAGE Displays a message in the command window. This is an alternative to WARNING, avoiding the automatic text "Warning: ", and also allowing for more flexible formatting, using FPRINTF.

It was developed with the intention of providing suppressible feedback during code execution requiring long running durations.
(e.g. Processing file 1 of 100...
Processing file 2 of 100... )

In this sense it can be used as a text alternative to WAITBAR.

Example Usage:

>> message('Hello')
Hello

>> message('Level 1','Hello')
Level 1
%behaves identically to FPRINTF

>> message('Level 1 %s','Hello')
Level 1 Hello

>> message('enable',{'Level 1'})
>> message('Level 1','Hello')
Hello

>> message('enable','Level 1')
>> message('off')
>> message('Level 1','Hello')
%no output returned
>> state = message('query','Level 1')
state =
