this files very imprtant

I have a problem in running the toolbox nnsysid. Actually I got the following messeges,If anyone knows the answer, then I would appreciate.

[w1,w2] = wrescale('nnoe',W1,W2,uscales,yscales,NN);
>> [thd,trv,fpev,tev,deff,pv] = ...
nnprune('nnoe',NetDef,W1,W2,u1s,y1s,NN,trparms,prparms,u2s,y2s);
Warning: Matrix is close to singular or badly scaled.
         Results may be inaccurate. RCOND = 1.639375e-016.

This tool is Good.
