Disabled Warning Message still Appears While Using Patternsearch

Dear all,

I disabled warning messages regarding a nearly singular matrix with "warning('off','MATLAB:nearlySingularMatrix')". However, while using patternsearch(), the corresponding warning output still appears and crushs my desired output. The warning output is just not set as a link in orange color as normal, but in black... Does anybody has an idea how to solve that?

Thanks and kind regards, Florian
