Hello!

I worked with the neural network toolbox until yesterday when suddenly I got a error message:

At first I thougt that somehow the data I feed into the neural network got corrupted. But after checking this I could rule it out as I cause. To make sure it is not the data I tried the sample data that comes with MATLAB and I get the same error message with the sample data.

If I try to call patternnet(10) in the command window I get the following error message:

>> net=patternnet(10)
Default value is not a member of type "nntype.performance_fcn".
Error using nnetParamInfo (line 28)
Reference to non-existent field 'net_read_only'.
Error in patternnet>get_info (line 85)
  info = nnfcnNetwork(mfilename,'Pattern Recognition Neural Network',fcnversion, ...
Error in patternnet (line 41)
if isempty(INFO), INFO = get_info; end

I have R2013b 64-bit. Does anybody have an idea what could be the reason that suddenly the neural network toolbox doesn't work anymore? I would very much appreciate your help.
