Hi, I have what I hope is a simple question. I am running some code which sometimes produces a MATLAB:nearlysingularmatrix warning. I have disabled this in the usual way (warning('off','MATLAB:nearlysingularmatrix'), which works fine under serial operation. When I run this program in a parfor loop, however, the warnings still get printed to the screen, which is annoying, in this form:

Warning: Matrix is close to singular or badly scaled.
Results may be inaccurate. RCOND = 3.860704e-017.
> In myfun at 145
In parallel_function>make_general_channel/channel_general at 871
In remoteParallelFunction at 31

How can I turn off this warning so that it is also turned off on my workers?

Thank you,
Jacob

You would have to turn off the warning on the workers too.
This might help:

Thanks! That worked perfectly.
