Undefined function or variable 'network'

When I try to run one of the demo's or, just one of the functions (feedforwardnet(10)), I get the following error:

Undefined function or variable 'network'

??? Undefined function or variable 'network'.

Error in ==> feedforwardnet>create_network at 99 net = network;

Error in ==> feedforwardnet at 67 net = create_network(param);

How do I solve this?

Well, is the variable network defined? If not, the obvious solution is to define it!

I had this same error message when using nntool. Check if you have the toolbox license. >license('checkout','nntool'); License checkout failed.

If you see this, you need to download the toolbox

Try rehashing your toolbox path in case something got corrupted:

rehash toolboxcache

The class network should exist on a path similar to this:

which -all network

C:\Program Files\MATLAB\R2012b\toolbox\nnet\nnet\@network\network.m % network constructor
