Reference to non-existent field 'net_read_only'

Hi everyone,

I am a beginner using neural network toolbox. I don't know why but my neural network stop working and keep return Reference to non-existent field 'net_read_only.

If I run the network by script it stop after

net = patternnet(hiddenLayerSize);

and return error:

 Default value is not a member of type "nntype.performance_fcn".

Would someone kindly help me through this problem.

Thank you

Do you have an older version of the NNTOOLBOX which does not contain PATTERNNET?

 lookfor patternnet

 help patternnet

 doc patternnet

If so, use NEWPR.

Hope this helps,

Thank you for formally accepting my answer
