MATLAB: How to turn warning off in parpool

parpoolwarnings

I am running a PSO optimization. Some of the particles are near to singular value in the calculation of a matrix. I really dont care about that is a usual warning. I tried the usual method of

warning off MATLAB:singularMatrix;
warning off MATLAB:nearlySingularMatrix

and

[a, MSGID] = lastwarn();
warning('off', MSGID)

but because is in the function i am having warnings for each processor. How can I turn off this warnings. It is slowing the process Note: full warning off also is not working.

Try parfevalOnAll to turn the warnings off on all workers after you open the pool but before you parfor

This change has been incorporated into the documentation in Release 2010a (R2010a). For previous releases, read below for any additional information:

The general method for suppressing a warning message is to issue the following command at the prompt:

warning('off', MSGID)

The string 'MSGID' is a unique identifier that corresponds to a particular warning message.

There are two ways to determine what a warning's identifier is, so that it can be suppressed later:

1) Just after the specific warning has been issued, run the following command:

[a, MSGID] = lastwarn();

This will save the message identifier to the variable MSGID. Then you can use the command given above to turn that particular warning off.

2) Turn on verbose warning messages with the following command:

warning on verbose

When warnings are displayed, they will include the command that can be used to turn that warning off.
