Hallo,
Can anyone explain why 'sim' command in neural network is not working in Matlab version 2015 and above? After training the network, I wanted to simulate the values to predict the accuracy of the network. I used the command :
y=sim(net,p); where y is the simulated values matrix of the input matrix p
When i try to do the same using the neural network toolbox, I was able to simulate the values but not able to use 'sim' as objective function for the subsequent optimization methods.
Regards, Bharath

Replace
train( net, p, t )
with reasonable variations of
[ net tr y e ] = train( net, p, t );
where y = net( x ) and e = t-y
Hope this helps.
Thank you for formally accepting my answer

You cannot use the names of MATLAB commands or functions for your own use. They are RESERVED.
Any of the commands
lookfor sim
help sim
doc sim
which sim
would have indicated a reserved name.
By the way, as you can gather from the help or doc documentation on fitnet, patternnet, etc the command y = sim(net,x) has been replaced by y = net(x). SIM is now used w.r.t. SIMULINK.
Hope this helps.

Your attachment is unreadable. Just cut and paste the code. Greg
