You can selectively enable or disable specific warning messages, as long as they have been given a message identifier, with the WARNING function using the state and 'message_id' input arguments. You can suppress all warning messages using the 'off' state option, with the argument 'all' in place of a message identifier. You can suppress only the last warning message in a similar manner, replacing 'all' with 'last'. Once you have suppressed warnings, you can enable the warning messages again using the 'on' state option.

For more information on the WARNING function and message identifiers, please refer to the following documentation:

MATLAB: How to suppress the table warning in R2017a

In MATLAB R2017a, the table warning suppression ID changed. While it used to be mapped to the ID 'MATLAB:table:ModifiedVarnames', it is now mapped to the ID 'MATLAB:table:ModifiedAndSavedVarnames'. You can find the last warning's ID with the following command:

 >> [a, MSGID] = lastwarn()
 a =
     'Variable names were modified to make them valid MATLAB identifiers. The original names are saved in the VariableDescriptions property.'
 MSGID =
     'MATLAB:table:ModifiedAndSavedVarnames'

So the following command will suppress the table warning as desired:

>> warning('OFF', 'MATLAB:table:ModifiedAndSavedVarnames')

You can use

warning('off','message_id')

to turn off a specific warning. You can use lastwarn to find out the message_id corresponds to the visualization block warning. Details can be found in the doc
